Research Gap

Definition:

Research gap refers to an area or topic within a field of study that has not yet been extensively researched or is yet to be explored. It is a question, problem or issue that has not been addressed or resolved by previous research.

How to Identify Research Gap

Identifying a research gap is an essential step in conducting research that adds value and contributes to the existing body of knowledge. Research gap requires critical thinking, creativity, and a thorough understanding of the existing literature . It is an iterative process that may require revisiting and refining your research questions and ideas multiple times.

Here are some steps that can help you identify a research gap:

• Review existing literature: Conduct a thorough review of the existing literature in your research area. This will help you identify what has already been studied and what gaps still exist.
• Identify a research problem: Identify a specific research problem or question that you want to address.
• Analyze existing research: Analyze the existing research related to your research problem. This will help you identify areas that have not been studied, inconsistencies in the findings, or limitations of the previous research.
• Brainstorm potential research ideas : Based on your analysis, brainstorm potential research ideas that address the identified gaps.
• Consult with experts: Consult with experts in your research area to get their opinions on potential research ideas and to identify any additional gaps that you may have missed.
• Refine research questions: Refine your research questions and hypotheses based on the identified gaps and potential research ideas.
• Develop a research proposal: Develop a research proposal that outlines your research questions, objectives, and methods to address the identified research gap.

Types of Research Gap

There are different types of research gaps that can be identified, and each type is associated with a specific situation or problem. Here are the main types of research gaps and their explanations:

Theoretical Gap

This type of research gap refers to a lack of theoretical understanding or knowledge in a particular area. It can occur when there is a discrepancy between existing theories and empirical evidence or when there is no theory that can explain a particular phenomenon. Identifying theoretical gaps can lead to the development of new theories or the refinement of existing ones.

Empirical Gap

An empirical gap occurs when there is a lack of empirical evidence or data in a particular area. It can happen when there is a lack of research on a specific topic or when existing research is inadequate or inconclusive. Identifying empirical gaps can lead to the development of new research studies to collect data or the refinement of existing research methods to improve the quality of data collected.

Methodological Gap

This type of research gap refers to a lack of appropriate research methods or techniques to answer a research question. It can occur when existing methods are inadequate, outdated, or inappropriate for the research question. Identifying methodological gaps can lead to the development of new research methods or the modification of existing ones to better address the research question.

Practical Gap

A practical gap occurs when there is a lack of practical applications or implementation of research findings. It can occur when research findings are not implemented due to financial, political, or social constraints. Identifying practical gaps can lead to the development of strategies for the effective implementation of research findings in practice.

Knowledge Gap

This type of research gap occurs when there is a lack of knowledge or information on a particular topic. It can happen when a new area of research is emerging, or when research is conducted in a different context or population. Identifying knowledge gaps can lead to the development of new research studies or the extension of existing research to fill the gap.

Examples of Research Gap

Here are some examples of research gaps that researchers might identify:

• Theoretical Gap Example : In the field of psychology, there might be a theoretical gap related to the lack of understanding of the relationship between social media use and mental health. Although there is existing research on the topic, there might be a lack of consensus on the mechanisms that link social media use to mental health outcomes.
• Empirical Gap Example : In the field of environmental science, there might be an empirical gap related to the lack of data on the long-term effects of climate change on biodiversity in specific regions. Although there might be some studies on the topic, there might be a lack of data on the long-term effects of climate change on specific species or ecosystems.
• Methodological Gap Example : In the field of education, there might be a methodological gap related to the lack of appropriate research methods to assess the impact of online learning on student outcomes. Although there might be some studies on the topic, existing research methods might not be appropriate to assess the complex relationships between online learning and student outcomes.
• Practical Gap Example: In the field of healthcare, there might be a practical gap related to the lack of effective strategies to implement evidence-based practices in clinical settings. Although there might be existing research on the effectiveness of certain practices, they might not be implemented in practice due to various barriers, such as financial constraints or lack of resources.
• Knowledge Gap Example: In the field of anthropology, there might be a knowledge gap related to the lack of understanding of the cultural practices of indigenous communities in certain regions. Although there might be some research on the topic, there might be a lack of knowledge about specific cultural practices or beliefs that are unique to those communities.

Examples of Research Gap In Literature Review, Thesis, and Research Paper might be:

• Literature review : A literature review on the topic of machine learning and healthcare might identify a research gap in the lack of studies that investigate the use of machine learning for early detection of rare diseases.
• Thesis : A thesis on the topic of cybersecurity might identify a research gap in the lack of studies that investigate the effectiveness of artificial intelligence in detecting and preventing cyber attacks.
• Research paper : A research paper on the topic of natural language processing might identify a research gap in the lack of studies that investigate the use of natural language processing techniques for sentiment analysis in non-English languages.

How to Write Research Gap

By following these steps, you can effectively write about research gaps in your paper and clearly articulate the contribution that your study will make to the existing body of knowledge.

Here are some steps to follow when writing about research gaps in your paper:

• Identify the research question : Before writing about research gaps, you need to identify your research question or problem. This will help you to understand the scope of your research and identify areas where additional research is needed.
• Review the literature: Conduct a thorough review of the literature related to your research question. This will help you to identify the current state of knowledge in the field and the gaps that exist.
• Identify the research gap: Based on your review of the literature, identify the specific research gap that your study will address. This could be a theoretical, empirical, methodological, practical, or knowledge gap.
• Provide evidence: Provide evidence to support your claim that the research gap exists. This could include a summary of the existing literature, a discussion of the limitations of previous studies, or an analysis of the current state of knowledge in the field.
• Explain the importance: Explain why it is important to fill the research gap. This could include a discussion of the potential implications of filling the gap, the significance of the research for the field, or the potential benefits to society.
• State your research objectives: State your research objectives, which should be aligned with the research gap you have identified. This will help you to clearly articulate the purpose of your study and how it will address the research gap.

Importance of Research Gap

The importance of research gaps can be summarized as follows:

• Advancing knowledge: Identifying research gaps is crucial for advancing knowledge in a particular field. By identifying areas where additional research is needed, researchers can fill gaps in the existing body of knowledge and contribute to the development of new theories and practices.
• Guiding research: Research gaps can guide researchers in designing studies that fill those gaps. By identifying research gaps, researchers can develop research questions and objectives that are aligned with the needs of the field and contribute to the development of new knowledge.
• Enhancing research quality: By identifying research gaps, researchers can avoid duplicating previous research and instead focus on developing innovative research that fills gaps in the existing body of knowledge. This can lead to more impactful research and higher-quality research outputs.
• Informing policy and practice: Research gaps can inform policy and practice by highlighting areas where additional research is needed to inform decision-making. By filling research gaps, researchers can provide evidence-based recommendations that have the potential to improve policy and practice in a particular field.

Applications of Research Gap

Here are some potential applications of research gap:

• Informing research priorities: Research gaps can help guide research funding agencies and researchers to prioritize research areas that require more attention and resources.
• Identifying practical implications: Identifying gaps in knowledge can help identify practical applications of research that are still unexplored or underdeveloped.
• Stimulating innovation: Research gaps can encourage innovation and the development of new approaches or methodologies to address unexplored areas.
• Improving policy-making: Research gaps can inform policy-making decisions by highlighting areas where more research is needed to make informed policy decisions.
• Enhancing academic discourse: Research gaps can lead to new and constructive debates and discussions within academic communities, leading to more robust and comprehensive research.

Advantages of Research Gap

Here are some of the advantages of research gap:

• Identifies new research opportunities: Identifying research gaps can help researchers identify areas that require further exploration, which can lead to new research opportunities.
• Improves the quality of research: By identifying gaps in current research, researchers can focus their efforts on addressing unanswered questions, which can improve the overall quality of research.
• Enhances the relevance of research: Research that addresses existing gaps can have significant implications for the development of theories, policies, and practices, and can therefore increase the relevance and impact of research.
• Helps avoid duplication of effort: Identifying existing research can help researchers avoid duplicating efforts, saving time and resources.
• Helps to refine research questions: Research gaps can help researchers refine their research questions, making them more focused and relevant to the needs of the field.
• Promotes collaboration: By identifying areas of research that require further investigation, researchers can collaborate with others to conduct research that addresses these gaps, which can lead to more comprehensive and impactful research outcomes.

Disadvantages of Research Gap

While research gaps can be advantageous, there are also some potential disadvantages that should be considered:

• Difficulty in identifying gaps: Identifying gaps in existing research can be challenging, particularly in fields where there is a large volume of research or where research findings are scattered across different disciplines.
• Lack of funding: Addressing research gaps may require significant resources, and researchers may struggle to secure funding for their work if it is perceived as too risky or uncertain.
• Time-consuming: Conducting research to address gaps can be time-consuming, particularly if the research involves collecting new data or developing new methods.
• Risk of oversimplification: Addressing research gaps may require researchers to simplify complex problems, which can lead to oversimplification and a failure to capture the complexity of the issues.
• Bias : Identifying research gaps can be influenced by researchers’ personal biases or perspectives, which can lead to a skewed understanding of the field.
• Potential for disagreement: Identifying research gaps can be subjective, and different researchers may have different views on what constitutes a gap in the field, leading to disagreements and debate.

What Is A Research Gap? (With Tips + Examples)

A research gap is a specific area within a field of study that remains unexplored or under-explored. Identifying a research gap involves recognizing where existing research is lacking or where there are unanswered questions that could provide opportunities for further investigation. Understanding research gaps is crucial for advancing knowledge, as it helps scholars and researchers focus their efforts on areas that can contribute significantly to their field.

What Is A Research Gap?

It is actually a question or any issue that needs to be solved by any pre-existing work or research in your area of study. A research gap can also exist where some new idea still needs to be studied.

Tips on Identifying Research Gap

Research always plays an essential role in acquiring more knowledge and addressing the gaps in different fields. When you are identifying a research gap, you are taking a very important step in the whole research process. This aids the researchers in contributing meaningful insights and triggers the knowledge boundaries.

Understanding the Literature You Are Studying: In order to identify any research gap, it is essential to have an excellent advertising of the preexisting literature in your study field.

Here, you need to conduct a review of many books, scholarly articles, conferences, and other relevant sources. In this way, you can get a good foundation as well as insights into any present state of in-depth knowledge in your own study area.

Defining Your Own Research Question: After getting a good knowledge of the pre-existing literature, you need to define a concise and clear idea of the research question. This research question needs to be very specific, attainable, measurable, time-bound and relevant. An acronym for this entire thing is known as SMART. This also needs to address any significant issue that still needs to be fully solved or adequately answered.

Identifying Your Study Objectives: Here, you need to identify the major objectives of your research paper. All these objectives need to be aligned with the identified research gap. These objectives always guide the researcher and aid you in determining the direction and scope of your research study.

Analyze the Existing Studies: Here, you need to analyze very carefully all the existing studies that are related to your research question. Here, it would help if you looked at the most common recurring findings, themes, and patterns of the discussed literature. Here, you also need to pay a lot of attention to the conflicted areas with the results, unanswered questions, and contradictory theories. These areas show the research gaps that can be explored later.

Consider The Practical Relevance: You always need to evaluate the very practical relevance of the research question as well as its potential impact on society. Here, it would help if you always considered the importance of addressing your own research gap as you identified it.

Here, you also need to assess whether your findings can contribute to the original theoretical framework and offer all the practical solutions for leading to the policy recommendations. These practical ads are relevant to the research paper and trigger its impact.

Consulting With the Experts and Peers: You always need to engage you’re discussing with your mentors, peers, and experts in your own field of study. Here, you always need to seek their opinions and perspectives on the research question to identify potential research gaps.

These can provide valuable insights into assumption challenges, and this helps you refine your research work. Your peers and experts can give you a new idea and help you identify the errors in your thinking.

Conducting Your Pilot Study: You need to conduct it to test the viability and feasibility of the research question. This pilot study provides you with feedback and data on the research design, approach and methodology.

This also helps you identify the potential limitations or challenges that need to be solved before conducting the full research studies.

Reflecting and Refining: You need to vividly reflect on the research progress to refine your research preferences. You need to add the objectives. As you go deeper into your research process, additional research gaps may be uncovered to refine your own research needs.

If you follow this process, you can adapt your own approach to ensure the research gaps.

As per the example of the research gap, identifying your research gap allows your research to contribute to gaining more knowledge to address the pre-existing limitations.

This way, you will understand the existing literature to define a crystal clear research statement. You can identify the research gaps by analyzing the existing studies to consider their relevance. According to the research gap finder, if you consult with your peers, doing all the pilot studies reflects on your research process progress.

If you follow the guide mentioned above, you can always embark on meaningful research studies to trigger your knowledge in your subject area and make a prominent contribution to your field.

Different Types of Research Gaps

Identifying research gaps is essential for advancing knowledge in any field. Research gaps are areas where more information is available or existing research needs to be more consistent or conclusive. Here are different types of research gaps:

• Evidence Gap

This gap occurs when no empirical evidence supports certain theories, practices, or interventions. It can also refer to areas where existing studies need to sufficiently cover the topic or lack rigorous methodological approaches.

Example: A need for randomized controlled trials on the effectiveness of a new drug.

• Knowledge Gap

This gap refers to areas where there is a deficiency in understanding or awareness about a particular topic. It can be due to outdated information, incomplete research, or the absence of research on emerging issues.

Example: Limited knowledge about the long-term effects of exposure to new environmental pollutants.

• Theoretical Gap

Theoretical gaps arise when existing theories do not fully explain certain phenomena or when there is a lack of theoretical frameworks to guide research in a particular area.

Example: More theoretical models need to be developed to explain the psychological impacts of social media usage on teenagers.

• Methodological Gap

Methodological gaps exist when current research methods are inadequate for addressing certain research questions or when there is a need for new or improved methodologies.

Example: More robust qualitative methods are needed to study the experiences of marginalized communities.

• Population Gap

This type of gap occurs when certain populations are underrepresented in research. It can involve demographics like age, gender, ethnicity, socioeconomic status, or geographic location.

Example: Lack of research on the mental health of older adults living in rural areas.

Geographical Gap

Geographical gaps refer to areas or regions that are under-researched. These gaps highlight the need for studies in different geographic contexts to understand local issues better.

Example: Limited studies on the effects of climate change in the Arctic regions.

Strategies to Identify Research Gaps:

• Literature Reviews: Comprehensive reviews can help identify where current research is lacking or inconsistent.
• Systematic Reviews and Meta-Analyses: These methods provide a structured approach to synthesize existing research and identify gaps.
• Expert Consultations: Discussions with experts in the field can uncover areas that require further investigation.
• Research Databases: Utilizing databases and citation analysis tools to track research trends and identify under-researched areas.
• Interdisciplinary Approaches: Engaging with multiple disciplines can reveal gaps that are not apparent within a single field.

Understanding and addressing these gaps is crucial for advancing research and knowledge across various domains.

What is a Research Gap Example?

A Research Paper Example gives you a very clear idea of how to find your research gaps and examples in textual forms. A few examples are given below:

• Context Healthcare: Although there have been enough researchers on the management of diabetes, there has been a research gap in understanding the impact of digital health interventions in the rural areas of Europe.
• Content environmental science: In a wealth of research regarding the huge environmental pollution caused by the use of plastics, there are fewer findings of how the plastic material really accumulates in certain areas like lakes, rivers, etc. and why these materials are never biodegradable.
• Context Education: The empirical research surrounding the online mode has become tremendously popular over the past few years. However, there needs to be more solid studies regarding the impact of the online learning process on the students who need special education. In each of these examples, you can see that the writer begins by acknowledging the preexisting reach results and then explains thoroughly the present area where the research gap really exists.

How to Find a Research Gap?

After getting a very clear idea of various types of research gaps, the vet’s next question comes to mind is how to find a research gap. There is a basic 2 step strategy to find the research gap.

In the beginning, you need to find a lot of literature reviews, meta-analyses, and systematic reviews covering your research area of interest. Moreover, it would help if you dug into the very recent journals for wrapping your head in your own knowledge area.

Here, you can also study the current theses and dissertations, especially those in the doctoral degree courses. A number of dissertation databases, such as Open Access, EBSCO, Pro-Quest, etc., are very useful in this regard. Here. You also need to ensure that you are always looking for the most recent sources.

After gathering a good collection of these resources, you need to focus on further research opportunities. In this section, you need to state explicitly where more studies are needed. It would help if you also looked at the present research study’s limitation areas and where the research gaps might exist.

Following this procedure will help you become oriented to the present research area. This can serve as a foundation for finding the potential research gaps. Then, you need to shortlist the main ideas and evaluate them as per the given topic. It would help if you also looked only for the recent articles here.

How to Deal with Literature Gap?

In any project, a literature review is always very important. It helps you in identifying your excusing knowledge, methods and theories in your own field. However, conducting a literature review has its own challenges.

• Defiling your research question: The very first step is to define your own research question very clearly and briefly. It will help you narrow your scope and focus on the crucial sources. It would help if you used less information here. Your research must always be very specific, answerable, and original. The research project always needs to have real objectives and a purpose.
• Searching and selecting the sources: Your next step is to search and select the sources. That is very much reliable and relevant to your research field. There are a number of databases, like keywords, search engines, etc., related to your study field. However, there are also a lot of limitations to these tools, like currency, coverage, and quality of the sources. Here, certain criteria have to be applied to filter the sources, such as relevance, authority, timeline, and accuracy of the information.
• Analyzing and synthesizing the literature: This is the third step, where you need to analyze and synthesize the literature you selected. Here, you need to summarize the sources and compare, contrast and critique them. In this section, you also need to look for the similarities and differences, the strengths and weaknesses, and the gaps and inconsistencies of the literature review paper. The writers can also identify the major trends, themes, and debates in the discussed field. These should also be related to your research question.
• Fill in the gaps after identifying them: This is the 4th step to filling the literature review research paper. This gap needs to be addressed or is under the researched area and is to be addressed by you with the help of your knowledge. These gaps can be filled by looking for the limitations, contradictions or controversies in the review. You can also do this by asking new questions or proposing new ideas. The gaps can also be filled by providing the newest evidence, arguments or even insights related to your field of study.
• Organizing and structuring the literature review: This is the 5th step of your review, where you need to organize and structure the whole paper in a compact and logical manner. Here, you always need to follow certain guidelines as given by your institute and use the best style and font. Proper headings, subheading citations, and traditions should also be used here. This will help your readers follow your arguments and understand what you want to say. A very clear introduction should also be written, along with a good conclusion and summary to highlight your writing.
• Refining and Revising: The literature review is the final step of writing your literature review. Here, you need to ensure that your review is quite accurate, concise and clear. You must check your literature review thoroughly to make it free from errors, gaps, or inconsistencies in language, content, or presentation. Here, you can also seek feedback from your peers, experts or supervisors in your own field. Their suggestions will help you in performing well. The whore literature review should be thoroughly proofread and edited before the final submission.

Last but not least, never copy from any source; it will be considered plagiarism, and your paper will be cancelled then and there. Thus, write only from your own creativity and not from the writing and articles of other writers.

How To Find A Research Gap, Quickly

A step-by-step guide for new researchers

By: Derek Jansen (MBA) | Reviewer: Eunice Rautenbach (DTech) | April 2023

If you’ve got a dissertation, thesis or research project coming up, one of the first (and most important) things you’ll need to do is find a suitable research gap . In this post, we’ll share a straightforward process to help you uncover high-quality, original research gaps in a very time-efficient manner.

Overview: Finding Research Gaps

• What exactly is a research gap?
• Research gap vs research topic
• How to find potential research gaps
• How to evaluate research gaps (and topics)
• Key takeaways

What is a research gap?

As a starting point, it’s useful to first define what we mean by research gap, to ensure we’re all on the same page. The term “research gap” gets thrown around quite loosely by students and academics alike, so let’s clear that up.

Simply put, a research gap is any space where there’s a lack of solid, agreed-upon research regarding a specific topic, issue or phenomenon. In other words, there’s a lack of established knowledge and, consequently, a need for further research.

Let’s look at a hypothetical example to illustrate a research gap.

Within the existing research regarding factors affect job satisfaction , there may be a wealth of established and agreed-upon empirical work within a US and UK context , but very little research within Eastern nations such as Japan or Korea . Given that these nations have distinctly different national cultures and workforce compositions compared to the West, it’s plausible that the factors that contribute toward job satisfaction may also be different. Therefore, a research gap emerges for studies that explore this matter.

This example is purely hypothetical (and there’s probably plenty of research covering this already), but it illustrates the core point that a research gap reflects a lack of firmly established knowledge regarding a specific matter . Given this lack, an opportunity exists for researchers (like you) to go on and fill the gap.

So, it’s the same as a research topic?

Not quite – but they are connected. A research gap refers to an area where there’s a lack of settled research , whereas a research topic outlines the focus of a specific study . Despite being different things, these two are related because research gaps are the birthplace of research topics. In other words, by identifying a clear research gap, you have a foundation from which you can build a research topic for your specific study. Your study is unlikely to resolve the entire research gap on it’s own, but it will contribute towards it .

If you’d like to learn more, we’ve got a comprehensive post that covers research gaps (including the different types of research gaps), as well as an explainer video below.

How to find a research gap

Now that we’ve defined what a research gap is, it’s time to get down to the process of finding potential research gaps that you can use as a basis for potential research topics. Importantly, it’s worth noting that this is just one way (of many) to find a research gap (and consequently a topic). We’re not proposing that it’s the only way or best way, but it’s certainly a relatively quick way to identify opportunities.

Step 1: Identify your broad area of interest

The very first step to finding a research gap is to decide on your general area of interest . For example, if you were undertaking a dissertation as part of an MBA degree, you may decide that you’re interested in corporate reputation, HR strategy, or leadership styles. As you can see, these are broad categories – there’s no need to get super specific just yet. Of course, if there is something very specific that you’re interested in, that’s great – but don’t feel pressured to narrow it down too much right now.

Equally important is to make sure that this area of interest is allowed by your university or whichever institution you’ll be proposing your research to. This might sound dead obvious, but you’ll be surprised how many times we’ve seen students run down a path with great excitement, only to later learn that their university wants a very specific area of focus in terms of topic (and their area of interest doesn’t qualify).

Step 2: Do an initial literature scan

Once you’ve pinned down your broad area (or areas) of interest, the next step is to head over to Google Scholar to undertake an initial literature scan . If you’re not familiar with this tool, Google Scholar is a great starting point for finding academic literature on pretty much any topic, as it uses Google’s powerful search capabilities to hunt down relevant academic literature. It’s certainly not the be-all and end-all of literature search tools, but it’s a useful starting point .

Within Google Scholar, you’ll want to do a few searches using keywords that are relevant to your area of interest. Sticking with our earlier example, we could use the key phrase “job satisfaction”, or we may want to get a little more specific – perhaps “job satisfaction for millennials” or “job satisfaction in Japan”.

It’s always a good idea to play around with as many keywords/phrases as you can think up.  Take an iterative approach here and see which keywords yield the most relevant results for you. Keep each search open in a new tab, as this will help keep things organised for the next steps.

Once you’ve searched for a few different keywords/phrases, you’ll need to do some refining for each of the searches you undertook. Specifically, you’ll need to filter the results down to the most recent papers . You can do this by selecting the time period in the top left corner (see the example below).

Filtering to the current year is typically a good choice (especially for fast-moving research areas), but in some cases, you may need to filter to the last two years . If you’re undertaking this task in January or February, for example, you’ll likely need to select a two-year period.

Step 3: Review and shortlist articles that interest you

Once you’ve run a few searches using different keywords and phrases, you’ll need to scan through the results to see what looks most relevant and interesting to you. At this stage, you can just look at the titles and abstracts (the description provided by Google Scholar) – don’t worry about reading the actual article just yet.

Next, select 5 – 10 articles that interest you and open them up. Here, we’re making the assumption that your university has provided you with access to a decent range of academic databases. In some cases, Google Scholar will link you directly to a PDF of the article, but in most cases, you’ll need paid access. If you don’t have this (for example, if you’re still applying to a university), you can look at two options:

Open-access articles – these are free articles which you can access without any journal subscription. A quick Google search (the regular Google) will help you find open-access journals in your area of interest, but you can also have a look at DOAJ and Elsevier Open Access.

DeepDyve – this is a monthly subscription service that allows you to get access to a broad range of journals. At the time of shooting this video, their monthly subscription is around $50 and they do offer a free trial, which may be sufficient for your project.

Step 4: Skim-read your article shortlist

Now, it’s time to dig into your article shortlist and do some reading. But don’t worry, you don’t need to read the articles from start to finish – you just need to focus on a few key sections.

Specifically, you’ll need to pay attention to the following:

• The abstract (which you’ve probably already read a portion of in Google Scholar)
• The introduction – this will give you a bit more detail about the context and background of the study, as well as what the researchers were trying to achieve (their research aims)
• The discussion or conclusion – this will tell you what the researchers found

By skimming through these three sections for each journal article on your shortlist, you’ll gain a reasonable idea of what each study was about, without having to dig into the painful details. Generally, these sections are usually quite short, so it shouldn’t take you too long.

Step 5: Go “FRIN hunting”

This is where the magic happens. Within each of the articles on your shortlist, you’ll want to search for a few very specific phrases , namely:

• Future research
• Further research
• Research opportunities
• Research directions

All of these terms are commonly found in what we call the “FRIN” section . FRIN stands for “further research is needed”. The FRIN is where the researchers explain what other researchers could do to build on their study, or just on the research area in general. In other words, the FRIN section is where you can find fresh opportunities for novel research . Most empirical studies will either have a dedicated FRIN section or paragraph, or they’ll allude to the FRIN toward the very end of the article. You’ll need to do a little scanning, but it’s usually pretty easy to spot.

It’s worth mentioning that naturally, the FRIN doesn’t hand you a list of research gaps on a platter. It’s not a silver bullet for finding research gaps – but it’s the closest thing to it. Realistically, the FRIN section helps you shortcut the gap-hunting process  by highlighting novel research avenues that are worth exploring.

This probably sounds a little conceptual, so let’s have a look at a few examples:

The impact of overeducation on job outcomes: Evidence from Saudi Arabia (Alzubaidi, 2020)

If you scroll down to the bottom of this article, you’ll see there’s a dedicated section called “Limitations and directions for future research”. Here they talk about the limitations of the study and provide suggestions about how future researchers could improve upon their work and overcome the limitations.

Perceived organizational support and job satisfaction: a moderated mediation model of proactive personality and psychological empowerment (Maan et al, 2020)

In this article, within the limitations section, they provide a wonderfully systematic structure where they discuss each limitation, followed by a proposal as to how future studies can overcome the respective limitation. In doing so, they are providing very specific research opportunities for other researchers.

Medical professionals’ job satisfaction and telemedicine readiness during the COVID-19 pandemic: solutions to improve medical practice in Egypt (El-Mazahy et al, 2023)

In this article, they don’t have a dedicated section discussing the FRIN, but we can deduct it based on the limitations section. For example, they state that an evaluation of the knowledge about telemedicine and technology-related skills would have enabled studying their independent effect on the perception of telemedicine.

Follow this FRIN-seeking process for the articles you shortlisted and map out any potentially interesting research gaps . You may find that you need to look at a larger number of articles to find something interesting, or you might find that your area of interest shifts as you engage in the reading – this is perfectly natural. Take as much time as you need to develop a shortlist of potential research gaps that interest you.

Importantly, once you’ve developed a shortlist of potential research gaps, you need to return to Google Scholar to double-check that there aren’t fresh studies that have already addressed the gap. Remember, if you’re looking at papers from two years ago in a fast-moving field, someone else may have jumped on it . Nevertheless, there could still very well be a unique angle you could take – perhaps a contextual gap (e.g. a specific country, industry, etc.).

Ultimately, the need for originality will depend on your specific university’s requirements and the level of study. For example, if you’re doing an undergraduate research project, the originality requirements likely won’t be as gruelling as say a Masters or PhD project. So, make sure you have a clear understanding of what your university’s expectations are. A good way to do this is to look at past dissertations and theses for your specific programme. You can usually find these in the university library or by asking the faculty.

How to evaluate potential research gaps

Once you’ve developed a shortlist of potential research gaps (and resultant potential research topics) that interest you, you’ll need to systematically evaluate  them  to choose a winner. There are many factors to consider here, but some important ones include the following:

• Originality and value – is the topic sufficiently novel and will addressing it create value?
• Data access – will you be able to get access to the sample of interest?
• Costs – will there be additional costs involved for data collection and/or analysis?
• Timeframes – will you be able to collect and analyse the data within the timeframe required by your university?
• Supervisor support – is there a suitable supervisor available to support your project from start to finish?

To help you evaluate your options systematically, we’ve got a topic evaluation worksheet that allows you to score each potential topic against a comprehensive set of criteria. You can access the worksheet completely free of charge here .

Recap: Key Takeaways

We’ve covered quite a lot of ground in this post. Here are the key takeaways:

• A research gap is any space where there’s a lack of solid, agreed-upon research regarding a specific topic/issue/phenomenon.
• Unique research topics emerge from research gaps , so it’s essential to first identify high-quality research gaps before you attempt to define a topic.
• To find potential research gaps, start by seeking out recent journal articles on Google Scholar and pay particular attention to the FRIN section to identify novel opportunities.
• Once you have a shortlist of prospective research gaps and resultant topic ideas, evaluate them systematically using a comprehensive set of criteria.

The Best Method In Identifying Research Gap: An In-depth Analysis

What is research gap.

A research gap refers to an area or topic that has not been sufficiently explored or studied, leaving unanswered questions or unresolved issues. This article will provide an overview of the research gaps concept and their significance in the research process. It will also discuss the importance of identifying research gaps and how they can be used to formulate research objectives and problem statements. Additionally, this section will explore various techniques and strategies for conducting research gap analysis and bridging the gap between existing knowledge and future research endeavors.

Background of Research Gap

In the world of research, identifying and addressing research gaps is a crucial step towards advancing knowledge and understanding in a particular field. A research gap refers to an area in the existing body of knowledge where there is a lack of research or unanswered questions. In other words, it is a gap in the literature that needs to be addressed through further research.

Research gaps can occur for various reasons, such as a lack of studies on a specific topic, contradictory findings in existing research, or the emergence of new ideas or concepts that have not been explored. Identifying research gaps is crucial for the advancement of knowledge and the development of new research questions . By filling these gaps, researchers can contribute to the existing body of knowledge and address unanswered questions.

Furthermore, research gaps provide opportunities for researchers to make significant contributions to their field by conducting innovative and impactful studies. Understanding the background of research gaps is essential for researchers to identify areas where their research can make a meaningful impact.

Significance of Research Gap

The research gap plays a crucial role in the field of academia and scientific research. It holds significant importance for researchers, scholars, and the overall advancement of knowledge.

Contributing to Knowledge and Developing New Theories

One of the primary reasons why the research gap is significant is that it identifies areas where there is a lack of knowledge or understanding. It highlights the gaps in existing research, indicating the need for further investigation and exploration. By identifying research gaps, researchers can contribute to the existing body of knowledge by filling in the missing pieces. This leads to the development of new theories, concepts, and insights that can enhance our understanding of a particular subject or field.

Fostering Innovation and Progress through Unexplored Areas

Furthermore, the significance of research gaps lies in their potential to drive innovation and progress. When researchers identify areas that have not been extensively studied, they have the opportunity to explore new ideas, methodologies, and approaches. This can lead to groundbreaking discoveries and advancements in various disciplines.

Efficient Utilization of Resources to Avoid Duplication

Moreover, research gaps also help in avoiding duplication of efforts. By identifying what has already been studied and what areas are yet to be explored, researchers can focus their efforts on addressing the gaps rather than repeating existing research. This ensures that resources are utilized effectively and efficiently.

Impacting Practical Applications and Real-World Solutions

Additionally, the significance of research gaps extends to the practical application of research findings. By addressing the gaps in existing knowledge, researchers can provide valuable insights and solutions to real-world problems. This can have a direct impact on industries, policy-making, and decision-making processes. In conclusion, the significance of research gaps cannot be overstated. They serve as catalysts for knowledge advancement, innovation, and practical application. By identifying and addressing these gaps, researchers contribute to the growth and development of their respective fields, ultimately benefiting society as a whole.

Research Gap Examples

Identifying research gaps is crucial for pursuing innovative research. There are various types of research gaps that can be found in existing literature.

Knowledge gaps

Sometimes, a research gap exists when there is a concept or new idea that hasn’t been studied at all. For example, in the field of psychology, there might be a lack of research on the effects of social media on mental health in adolescents.

Conceptual gaps

Conceptual gaps occur when there is a lack of understanding or clarity about a particular concept or theory. For instance, in the field of economics, there might be a research gap in understanding the relationship between income inequality and economic growth.

Methodological gaps

Methodological gaps refer to the absence of appropriate research methods or techniques to study a specific phenomenon. For example, in the field of biology, there might be a research gap in developing a reliable method to detect a certain type of genetic mutation.

Data gaps occur when there is a lack of available data or insufficient data to address a research question. For instance, in the field of climate science, there might be a research gap in obtaining long-term temperature data for a specific region.

Practical gaps

Practical gaps exist when there is a discrepancy between theoretical knowledge and practical application. For example, in the field of education, there might be a research gap in implementing effective teaching strategies for students with learning disabilities.

Research Gap Analysis Techniques

Carry out a comprehensive literature review.

There are several techniques that can be used to identify research gaps. One common technique is conducting a comprehensive literature review, where researchers examine existing research papers, articles, books, and other relevant sources. By analyzing these materials, researchers can pinpoint what has already been explored and identify areas that require further investigation.

Examining Limitations and Contradictions in Existing Studies

During the literature review, researchers should pay attention to the limitations and gaps in the existing studies. These limitations can include unanswered research questions, contradictory findings, methodological issues, or areas that have not been explored in depth. Researchers can also gain insights by comparing and contrasting the findings, methodologies, and conclusions of different studies within their field, which helps in building a more complete understanding of the topic.

Exploring Interdisciplinary Insights to Identify Gaps

Additionally, researchers can seek inspiration from interdisciplinary fields or related disciplines to identify research gaps. Sometimes, a research gap in one field may have been addressed in another field, and researchers can draw upon these insights to identify areas that have not been explored within their own field. It is important to note that identifying research gaps is not a one-time process. As new studies are published and the field evolves, new gaps may emerge. Therefore, researchers should continuously update their knowledge and review the literature to stay informed about the latest developments and identify new research gaps.

Utilizing Surveys and Interviews for Direct Insights

Another technique is conducting surveys or interviews . This allows researchers to gather information directly from individuals who are knowledgeable in the field. Surveys can be distributed to a large number of participants, while interviews provide more in-depth insights from a smaller group of experts. By collecting data through surveys or interviews, researchers can identify gaps in knowledge or areas where more research is needed. Focus groups are another effective technique for conducting a research gap analysis. In a focus group, a small group of individuals with relevant expertise or experience is brought together to discuss a specific topic. Through group discussions and interactions, researchers can gain valuable insights and identify gaps in knowledge or areas that require further investigation.

Employing Quantitative Analysis to Discover Data Gaps

Quantitative analysis techniques, such as statistical analysis, can also be used to identify research gaps. By analyzing existing data sets, researchers can identify patterns, trends, or gaps in the data that may indicate areas where further research is needed. This type of analysis can provide valuable insights into the gaps in existing knowledge and guide future research directions.

Applying Gap Analysis Frameworks for Structured Assessment

In addition to these techniques, researchers can also use gap analysis frameworks or models to systematically identify and analyze research gaps. These frameworks provide a structured approach to assess the current state of knowledge, determine the desired future state, and identify the gaps that need to be addressed. By using a framework, researchers can ensure a comprehensive analysis of research gaps and develop strategies to bridge those gaps.

Research Gap and Problem Statement

A research problem is a specific issue or question that a researcher wants to investigate. It is the foundation of a research study and provides a clear direction for the research process. The identification of a research gap often leads to the formulation of a research problem.

The problem statement is a constructed sentence that defines the research problem and guides the research question. It helps to clarify the purpose of the study and provides a framework for the research design and research methodology. By addressing the research gap through the problem statement, researchers can contribute to the existing body of knowledge and fill the void in the literature. The research problem becomes the focal point of the study, and the research gap serves as the motivation for conducting the research.

Identifying a research gap and formulating a problem statement are crucial steps in the research process. They ensure that the research study is relevant, meaningful, and contributes to the advancement of knowledge in the field. As a key component of the research framework , the problem statement integrates directly into the overall structure that guides the entire research process, ensuring that all aspects of the investigation are aligned with the identified gaps and research questions.

Bridging the Research Gap

Bridging the research gap is crucial for the advancement of knowledge and the improvement of various fields. It involves closing the divide between research findings and their practical application in real-world settings. By bridging this gap, researchers can ensure that their work has a meaningful impact on society and that it is effectively utilized by practitioners and policymakers.

Effective Collaboration between Researchers and Practitioners

There are several strategies and approaches that can be employed to bridge the research gap. One practical way is to establish collaborations and partnerships between researchers and practitioners. By working together, researchers can gain valuable insights from practitioners’ experiences and expertise, while practitioners can benefit from the latest research findings and evidence-based practices. This collaboration can lead to the development of more relevant and effective solutions to real-world problems.

For facilitating such connections and collaborations, platforms like Researchmate.net are invaluable resources, providing the tools and community needed to bring together researchers and practitioners from diverse fields.

Intermediary Organizations in Facilitating Research Application

Another approach to bridging the research gap is through the use of intermediary organizations. These organizations act as a bridge between researchers and practitioners, facilitating the translation and dissemination of research findings into practical applications. They can provide training, resources, and support to practitioners, helping them to implement evidence-based practices in their work. Intermediary organizations also play a crucial role in promoting knowledge exchange and collaboration between researchers and practitioners.

Enhancing Communication and Knowledge Transfer in Research

Furthermore, bridging the research gap requires effective communication and knowledge transfer. Researchers need to communicate their findings in a clear and accessible manner, using language that is understandable to practitioners and policymakers. This can be achieved through the use of plain language summaries, policy briefs, and other forms of knowledge translation.

Engaging with Practitioners and Policymakers

Additionally, researchers should actively engage with practitioners and policymakers, seeking their input and feedback to ensure that research findings are relevant and applicable to real-world contexts.

In conclusion, exploring the research gap is a critical step in the research process. It helps researchers identify areas where further investigation is needed, contributes to the advancement of knowledge, and drives innovation. By understanding the research gap, researchers can make meaningful contributions to their field and address unanswered questions. Bridging the research gap requires collaboration and commitment from all stakeholders, but the potential benefits are immense.

How do I find a research gap for my thesis?

If you are just starting your bachelor’s or master’s thesis, chances are you have heard about finding a “research gap.” In this blog, we will explain what a research gap is, the four most common types of research gaps, and how to identify a suitable research gap.

What is a research gap?

A research gap refers to an unanswered question or unresolved problem in a field of study, indicating a lack of existing research in that area. A research gap can also exist when a substantial amount of existing research has been conducted, but the findings of the studies point in different directions. For example, suppose your research focuses on identifying the cause (or causes) of a specific disease. Upon reviewing the literature, you find that certain studies conclude that cigarette smoking is a significant factor. However, you also come across numerous studies that find no association between smoking and the disease. In such a case, you may be dealing with a research gap.

The different types of research gaps We distinguish four most common types of research gaps:

• The classical research gap
• The disagreement research gap
• The contextual research gap (most popular among thesis writers!)

The methodological research gap

1. the classical research gap.

This research gap occurs when there is a new concept or phenomenon that has not been extensively studied or not at all. For example, when a new social media platform is launched, there is an opportunity to explore its impact on users, how it can be used for marketing, its influence on society, and so on. The same applies to new technologies, new communication tools, new therapies, etc. Always try to delimit your research well. For a thesis, investigating an entirely new therapy, for example, is often too broad and extensive. Also, keep in mind that you will need to rely on adjacent literature to build your literature review. You won’t find many existing studies directly related to your topic.

2. The disagreement research gap

As the name suggests, the disagreement research gap arises when there are conflicting or contradictory findings in the existing research regarding a specific research question. The example we described above about the causes of a disease is an example of this type of research gap. Importantly, for this type of research gap, there must be different conflicting findings. In other words, a situation where 95% of the articles find one result and 5% find the opposite result would not really constitute a disagreement in the literature.

3. The contextual research gap

The third type of research gap is the contextual gap. Simply put, a contextual research gap exists when you find a considerable amount of existing research on a specific topic, but there is a lack of research in specific contexts. This could include:

• A specific population – perhaps a certain age group, gender, or ethnicity.
• A geographic area – for example, a city, country, or region.
• A particular time period – maybe most studies were conducted many years or even decades ago, and the landscape has changed.

Many thesis students choose this type of research gap because it allows them to base their research on existing literature and possibly even use existing questionnaires. It is important to clearly justify in your thesis why you expect differences in the specific context you choose. Make sure you can explain clearly why your chosen context is “different” from existing studies and why it could reasonably lead to different findings.

As the name suggests, this type of research gap arises due to the research methodology or design of existing studies. You may conclude that the methodology of existing studies is somehow inadequate or that they lack a certain perspective. For example, you may describe that the majority of existing research has adopted a quantitative approach and that there is, therefore, a lack of insight that a qualitative study could provide. Alternatively, you could describe that existing studies have mainly provided a snapshot of the situation, while a longitudinal approach could help uncover how variables have changed over time.

How to find a research gap?

Now that you have a clearer understanding of the different types of research gaps, the next question is, of course, “how do you find these research gaps?” Here, we describe a basic two-step strategy to help you find the research gap.

As a starting point, you need to gather as much recent literature reviews, systematic reviews, and meta-analysis articles as possible that relate to your topic. It is also a good idea to look at recent dissertations. There are several databases that share dissertations (such as OATD – Open Access Theses and Dissertations). Make sure to review the most recent sources possible; otherwise, the research gaps you find may have already been filled by other researchers. Once you have collected a substantial number of articles, focus on reading the discussion section and pay attention to anything they mention about “future research.” In the discussion, researchers will explicitly indicate areas where further studies are needed – in other words, your potential research gap. You can also look for the “limitations” they describe, as this often provides ideas for the methodological research gap. By following this process, you familiarize yourself with the current state of research, which will lay the foundation for identifying the research gap.

Tip: Go on a “FRIN hunt.” FRIN stands for “further research is needed.” Once you have found several relevant articles, search for specific keywords:

• Future research
• Further research
• Research opportunities
• Research directions

These terms are often found in what we call the “FRIN” section. Some articles have a dedicated FRIN section or paragraph, or they are mentioned in the discussion.

We wish you success in finding the research gap! If you need any assistance or have other questions, feel free to ask.

Steps for identifying research gaps in the literature

Your Master's thesis should make a significant, novel contribution to the field. Your thesis hypothesis should address a  research gap which you identify in the literature, a research question or problem that has not been answered in your research area of interest. This shows that you have developed expertise in the body of knowledge and theoretical issues in your chosen research area. 

Step 1: Focus Your Research Area

Before you start trying to identify gaps in the literature, you need to figure out what your area of interest is, and then focus and narrow that research area. If you don't narrow down your initial research area of interest, you'll end up wanting to research everything. You'll overwhelm yourself with all the research gaps you find because there are still a lot of unanswered research questions out there. 

• Do some exploratory research  on your broad research idea in your course textbook, class notes, in meta-analysis, systematic, and literature reviews, and  PsycINFO  to identify more specific issues and arguments in your research area and possible relationships between them.
• Read ebooks  to get the "big picture" about the research area you're interested in studying. Books and ebooks provide detailed information on your research area, put your research area in context, provide summaries of research, and help you identify major themes and relationships for your study.
• Ask your advisors and other faculty  about possible topics or issues within your research area of interest. That being said, you're going to spend over a year immersed in work on your thesis, so make sure you  choose issues because you find them deeply interesting , not just because your advisor recommended them.

Step 2: Read, Read, and then Read Some More

Read (a lot of) research articles : this is going to be time-demanding, but you really do need to read through a lot of research articles in your research area to become an expert in it. That being said, what you use from the articles that you read should relate directly back to your focused research questions and hypothesis. Don't waste your time getting sidetracked by issues that don't relate to your research questions and hypothesis.

• Go to  Start Finding Sources ,  Search Databases , and  Browse Journals  to find journal articles for your research area
• Pay close attention to Introductions , in which authors explain why their research is important, and Suggestions for Future Research , in which authors point readers to areas which lack investigation or need future examination

Follow the research trails  of seminal articles and authors using Web of Science and Scopus:

• In Scopus , click on Document Search , enter the article title, click on the article title in the list of search hits, then click on View all ~ citing documents link in the right sidebar for a list of articles that have cited this article
• In Web of Science , enter the article title and choose Title from the right drop down menu , then click on the Times Cited number next to the article to see a list of articles that have cited this article
• In Scopus , click on Author Search , enter the last name and first initial(s) of the author, click on the author's name in the list of search hits, then click on Cited By ~ documents for a list of articles that have cited this author
• In Web of Science , enter the author name and choose Author from the right drop down menu , then click on the Times Cited number next to each article to see a list of articles that have cited this author's article

Read meta-analyses, literature reviews,  and  systematic reviews : these papers delve deep into the literature, examining the trends and changes over a long period of time in your research area and summaries of previous research findings.

• In PsycINFO , click on literature review, systematic review, and  meta analysis  under the Methodologies heading in the sidebar to the right of the list of search hits 
• In CINAHL , add systematic reviews to your search 
• In Web Of Science , check the box beside Review under the Document Type heading in the sidebar to the right of the list of search hits

Step 3: Map out the Literature :

Keep track of what the authors told you and the questions that occur to you whenever you read anything - an article, a book, a book chapter, a dissertation, etc. This will also help you write your thesis introduction later on and help you avoid  unconscious plagiarism .Some more tips:

• Use mind maps, tables, charts, pictures, post-it notes to map out the literature, whatever works for you. 
• Research each of your questions to see if there are people out there who had the same questions and found answers to them
• Science Direct , Web of Science , and Wiley Online Library databases help you follow the research trail by listing articles that have since cited the research article you're reading

If you find don't find any answers to one of your questions, you've probably found a research gap from which you can develop a thesis hypothesis and experimental project. Get feedback from your advisors before you get too carried away, though!

• Get started by considering your central thesis question 
• How do the sources you've found connect to that question and help you answer it?
• How do the sources connect to and build off of one another?

Identifying a research gap for your thesis or dissertation

If you have an upcoming dissertation, thesis, or research project, it is crucial to find an appropriate research gap as one of your initial and significant steps. This article will provide you with a simple technique for discovering high-quality and unique research gaps in a time-effective manner. Because finding a relevant research gap first is one of the best thesis writing tips to give in the beginning!

What is a research gap?

To begin, let’s establish what we mean by the term “research gap” so that we are all on the same page. The expression is often used loosely by both students and academics. Essentially, a research gap is a space where there is a deficiency of reliable and widely accepted research on a particular topic, issue, or occurrence. This implies that there is an absence of established knowledge and, as a result, further investigation is required.

The fundamental idea is that a research gap indicates an absence of well-established understanding concerning a particular subject. With this absence, there is a chance for researchers like yourself to step in and bridge the gap.

Is it the same as a research topic ? Not entirely, they are related though. A research gap pertains to an area where there is still no conclusive research whereas a research topic identifies the focus of a particular study. Though separate in concept, they are connected because research gaps are the starting point of research topics. Hence, by determining a clear research gap, one can establish the foundation from which a research topic for a particular study can be formed. While a single study may not completely resolve the entire research gap, it can contribute to it.

6 steps towards identifying a research gap

In order to discover potential research topics , it is essential to understand what a research gap is and how to find it. It is important to note that there are various ways to find a research gap, and this is just one of them. Although it may not be the best method, it is a relatively quick way to identify opportunities.

Step 1: Focus on an area of interest

The first step is to choose a general area of interest. It is unnecessary to be very specific at this stage, but it is vital to ensure that the university approves of the chosen area. Many students make the mistake of exploring a topic without checking if it meets the required criteria.

Step 2: Scoping search

In order to begin your research on a particular area of interest, the second step is to conduct a preliminary search of academic literature using Google Scholar. This tool enables you to search for academic materials on a wide range of topics by utilizing Google’s advanced search capabilities. Although it’s not the definitive search tool, it is a good starting point. When you enter Google Scholar, you should use relevant keywords that are specific to your area of interest. Try experimenting with different keywords to see which ones yield the most relevant results. Once you conduct initial searches, you will need to refine the results by choosing the most recent papers from the filtering options in the top left of the screen.

It is generally a good idea to limit your search results to the last few years, particularly if you are researching a rapidly-evolving topic. However, there may be instances where your search needs to be more inclusive.

Step 3: Evaluate and narrow down articles that capture your attention.

After conducting multiple searches with varying keywords and phrases, you should skim through the results to determine which articles are most relevant and interesting to you. At this point, you may solely observe the titles and abstracts without delving into the actual content. From there, choose around 5 to 10 articles that pique your interest and access them.

Step 4: Selective reading

In Step 4, you should begin reading your selected articles. You do not need to read them in their entirety, but instead focus on certain sections such as the abstract, introduction, and discussion or conclusion. These sections will provide you with a general understanding of the study’s context, research aims, and findings. Skimming through these sections for each article on your list should not take long and will save you from going into excessive detail.

Step 5: FRIN

Step 5 involves searching for specific phrases known as FRIN (further research is needed) in the articles on your shortlist. The FRIN section is where researchers explain what other researchers can do to build on their study or research area. It provides fresh opportunities for novel research and is usually found towards the end of the article. While it doesn’t provide a complete list of research gaps, it highlights avenues worth exploring and helps shortcut the gap-hunting process. Examples of FRIN phrases include future research, research opportunities, and research directions.

To find interesting research gaps, use the FRIN-seeking process on your shortlisted articles. Be prepared to read through a large number of articles and allow your area of interest to shift naturally. Once you have shortlisted potential research gaps, double-check Google Scholar to ensure that no fresh studies have recently addressed the gap. However, even if someone has already addressed the gap, there could still be a unique angle that you could explore. It is important to determine your university’s specific requirements for originality, which may differ based on the level of study. You can get a clear understanding of your university’s expectations by reviewing past dissertations and theses for your specific programme, which are available in the university library or by asking the faculty.

Step 6: Evaluate and decide

Once you have identified several possible research gaps and topics that interest you, it is necessary to carefully assess them to determine the best option. This evaluation process requires consideration of various factors such as the originality and potential value of the topic, the accessibility of necessary data, potential costs associated with data collection and analysis, time constraints, and the availability of a supportive supervisor.

The post covers a lot of information. Here are the main points:

• A research gap refers to an area lacking solid, agreed-upon research on a specific topic, issue, or phenomenon.
• Unique research topics arise from research gaps, so it is important to first identify high-quality research gaps before defining a topic.
• To find potential research gaps, search for recent journal articles on Google Scholar, paying attention to the FRIN section to identify new opportunities.
• Once a shortlist of potential research gaps and topic ideas is created, systematically evaluate them using a broad set of criteria.

How to identify research gaps and include them in your thesis?

A thesis is an investigation that adheres to the principles of academic writing . It is critically evaluated on its reliability and significance for the industry (Chandra, 2017). The thesis research provides new insights into academia by reviewing existing research.

In this process, it is essential to identify the research gap. Research gaps are the centre of any research, determining the areas which lack crucial information.

Research gaps also help to frame:

The purpose of identifying research gaps in a thesis

A research gap is a problem that has not been addressed or answered in previous studies in the form of books, journal articles or reports. For instance, presently, there is a lack of research on the long-term effects of the Covid-19 vaccine. This can be a research gap in many studies such as social sciences, biotechnology, and medicine. Such problems need citation analysis and systematic review (Tsoulfas, 2021). To formulate an information-driven thesis, it is important to recognize the area or the topic that is unexplored or has insufficient information. Often research gaps in a thesis are confused with research questions and problem statements. However, there are fundamental differences in these concepts. The sole purpose of a research gap is to summarise problems with outdated or primitive studies. It is a part of the thesis introduction chapter and can range from 200 to 1000 words in length.

How to devote a section for research gaps in a thesis?

The first step in preparing the research gaps section is to outline the general state of knowledge and research in the field of study. This step helps in building the outline for the aspects that could be relevant to the research field.

The second step involves a thorough reading of earlier research and publication on the topic. For this, the researcher can refer to journal articles, library books, or reports. This step also involves consulting your supervisor.

Further, as per the reviewed articles, a viewpoint about the given topic must be framed by listing all relevant information.

Lastly, the need or significance of addressing the listed gaps should be presented.

Start the research gaps in a thesis with a summary of existing research findings. It does not need a detailed elaboration of the situation. For instance, statistics can be skipped. Similarly, you do not need to explain concepts or theories in this section. Next, state the limitations or lacuna in the area of research. This section needs more elaboration like who, what, when, where, why and how should be discussed. Each gap must be stated separately. For instance, consider these 3 gaps:

• there is a lack of research in your country’s context,
• there is a lack of empirical evidence and,
• there is a lack of consensus,

each should be explained separately. It should be structured in the form of citations wherever necessary. The writing pattern should move from generic to specific thus targeting the research problem for the thesis.

Points to avoid

• Too much description and analysis of the previously done studies must be avoided to keep the thesis research gap indicative and emblematic.
• Avoid giving too much statistical information.
• Avoid not reading enough. Identifying a research gap needs thorough reading, not skimping through facts.
• Avoid failing to accurately identify the need for further study and the lack of a persuasive framework for the identification of the research gap.
• Avoid not using enough citations for supporting the identified lacuna.
• Avoid not stating the significance of the identified gaps.

An example of research gaps in a thesis

Case topic: Impact of transformative heritage destinations on changing personal values of tourists

Travel behaviour today has shifted from global consumerism to a more meaningful and personalized experience. This has amplified the demand for heritage tourism, i.e. the movement of a person to places of cultural attraction away from their normal residential place to gain new experiences and information for satisfying cultural needs (G Richards, 2003; Rosenfeld, 2008). Tourists are also seeking transformative travel experiences which lead to positive changes in their values and attitudes. PineII & Gilmore (1999) have identified that heritage tourism is responding towards fulfilling the transformation needs of tourists. However, the lack of empirical evidence on the contribution of transformative heritage tourism in changing the personal values of tourists is restricting the formulation of strategies that can boost its growth.

Moreover, researchers have determined that authenticity, awareness, nostalgia, and satisfaction have a relationship with transformative effects and heritage tourism. Therefore, these factors may be interlinked. But despite this, not many academic studies have focused on addressing these tourist factors’ impact on the linkage between heritage tourism and transformative effect. This is another critical research gap.

Different Types of Research Gaps

Research gaps are areas where knowledge is lacking or where existing research could be expanded. Identifying and addressing these gaps is crucial for advancing knowledge in any field. Here are the different types of research gaps:

1. Evidence Gap

Definition : An evidence gap occurs when there is a lack of empirical data to support conclusions or theories. This gap signifies areas where more research is needed to provide solid evidence for or against a hypothesis.

Example : Limited studies on the long-term effects of a new medication.

2. Knowledge Gap

Definition : A knowledge gap refers to a lack of understanding or awareness about a specific topic. This gap often highlights areas where research has not yet been conducted or where findings are inconsistent.

Example : Insufficient knowledge about the impact of social media on mental health among teenagers.

3. Practical-Knowledge Gap

Definition : This gap arises when there is a disconnect between theoretical research and practical application. It points to areas where findings from research have not been implemented in real-world settings or where practical challenges are not addressed by existing research.

Example : Theoretical models for disaster management that are not tested in actual disaster scenarios.

4. Methodological Gap

Definition : A methodological gap is identified when current research methods are inadequate to address certain research questions. This gap indicates the need for new or improved research methods.

Example : The need for longitudinal studies to better understand the progression of chronic diseases.

5. Policy Gap

Definition : A policy gap occurs when research does not inform policy or when there is a lack of research supporting existing policies. This gap often highlights the need for research that can influence or evaluate policy decisions.

Example : Lack of research on the effectiveness of policies aimed at reducing carbon emissions.

6. Population Gap

Definition : This gap is present when certain populations or demographic groups are underrepresented in research. It calls attention to the need for more inclusive research that considers diverse populations.

Example : Underrepresentation of elderly populations in clinical trials for new medications.

7. Theory Gap

Definition : A theory gap is found when there is a lack of theoretical framework to explain certain phenomena. This gap suggests the need for developing or refining theories to better understand specific issues.

Example : Incomplete theoretical explanations for the rise of extremism in modern societies.

8. Contextual Gap

Definition : A contextual gap exists when research does not take into account the context in which a phenomenon occurs. This gap highlights the need for studies that consider environmental, cultural, or situational factors.

Example : Studies on education methods that do not consider cultural differences in learning styles.

9. Perspective Gap

Definition : This gap arises when certain perspectives or viewpoints are missing from the research. It emphasizes the need for more diverse viewpoints to provide a comprehensive understanding of a topic.

Example : Limited perspectives from minority groups in research on workplace diversity.

10. Data Gap

Definition : A data gap is identified when there is a lack of available data or when existing data is insufficient to support research conclusions. This gap indicates the need for more extensive data collection and analysis.

Example : Insufficient data on climate change impacts in specific geographic regions.

Gap Statements

  A gap is something that remains to be done or learned in an area of research; it’s a gap in the knowledge of the scientists in the field of research of your study. Every research project must, in some way, address a gap–that is, attempt to fill in some piece of information missing in the scientific literature. Otherwise, it is not novel research and is therefore not contributing to the overall goals of science.

Identify the gap.

  A gap statement is found in the Introduction section of a journal article or poster or in the Goals and Importance section of a research proposal and succinctly identifies for your audience the gap that you will attempt to address in your project.

A gap might be a lack of understanding about how well a particular instrument works in a certain situation. It could be introducing a new method that needs to be tested. Or it could be that you are studying a whole new organism, system, or part of a process. Your project may also address multiple gaps, in which case you should be sure to identify each of them clearly!

In a class, you might not always be studying something brand “new.” But, in most cases, you should still try to come up with something unique about your project, however small. Talk to your professor about what they expect for your gap statement if nothing seems to work.

Here, the authors signal to us that this is a gap because they use the words “has not yet been clarified.” Other phrases that might help you identify (or form!) a gap statement are:

• …has/have not been… (studied/reported/elucidated)
• …is required/needed…
• …the key question is/remains…
• …it is important to address…

Fill the gap.

  Once you identify the gap in the literature, you must tell your audience how you attempt to at least somewhat address in your project this lack of knowledge or understanding . In a journal article or poster, this is often done in a new paragraph and should be accomplished in one summary statement, such as:

Therefore, the purpose of this study was to determine the effects of lead on the hepatobiliary system, especially on the liver and on the gallbladder (adapted from Sipos et al. 2003 ).

You’ll often find that the first sentence of the last paragraph in a paper’s introduction will start somewhat like this, indicating the gap fill.  

Remember–always keep your voice professional! Colloquial phrases such as “we looked into” or “we checked if” should be avoided when introducing your gap fill.

So let’s look at this idea in context by looking at some examples from a couple of types of papers. The gap statements are underlined; the fills are italicized.  

In the second and third examples, the gap may be a little less obvious–it doesn’t use any phrases to signal to you that there’s something missing, such as “has not been clarified” or “have not been reported.” But because of the way the paragraph is laid out–following the conventions of our move structures–we can see that the underlined section of text is indeed the missing information in the literature that the group sought to address in their project.

Identifying Research Gaps to Pursue Innovative Research

This article is an excerpt from a lecture given by my Ph.D. guide, a researcher in public health. She advised us on how to identify research gaps to pursue innovative research in our fields.

What is a Research Gap?

Today we are talking about the research gap: what is it, how to identify it, and how to make use of it so that you can pursue innovative research. Now, how many of you have ever felt you had discovered a new and exciting research question , only to find that it had already been written about? I have experienced this more times than I can count. Graduate studies come with pressure to add new knowledge to the field. We can contribute to the progress and knowledge of humanity. To do this, we need to first learn to identify research gaps in the existing literature.

A research gap is, simply, a topic or area for which missing or insufficient information limits the ability to reach a conclusion for a question. It should not be confused with a research question, however. For example, if we ask the research question of what the healthiest diet for humans is, we would find many studies and possible answers to this question. On the other hand, if we were to ask the research question of what are the effects of antidepressants on pregnant women, we would not find much-existing data. This is a research gap. When we identify a research gap, we identify a direction for potentially new and exciting research.

How to Identify Research Gap?

Considering the volume of existing research, identifying research gaps can seem overwhelming or even impossible. I don’t have time to read every paper published on public health. Similarly, you guys don’t have time to read every paper. So how can you identify a research gap?

There are different techniques in various disciplines, but we can reduce most of them down to a few steps, which are:

• Identify your key motivating issue/question
• Identify key terms associated with this issue
• Review the literature, searching for these key terms and identifying relevant publications
• Review the literature cited by the key publications which you located in the above step
• Identify issues not addressed by  the literature relating to your critical  motivating issue

It is the last step which we all find the most challenging. It can be difficult to figure out what an article is  not  saying. I like to keep a list of notes of biased or inconsistent information. You could also track what authors write as “directions for future research,” which often can point us towards the existing gaps.

Different Types of Research Gaps

Identifying research gaps is an essential step in conducting research, as it helps researchers to refine their research questions and to focus their research efforts on areas where there is a need for more knowledge or understanding.

1. Knowledge gaps

These are gaps in knowledge or understanding of a subject, where more research is needed to fill the gaps. For example, there may be a lack of understanding of the mechanisms behind a particular disease or how a specific technology works.

2. Conceptual gaps

These are gaps in the conceptual framework or theoretical understanding of a subject. For example, there may be a need for more research to understand the relationship between two concepts or to refine a theoretical framework.

3. Methodological gaps

These are gaps in the methods used to study a particular subject. For example, there may be a need for more research to develop new research methods or to refine existing methods to address specific research questions.

4. Data gaps

These are gaps in the data available on a particular subject. For example, there may be a need for more research to collect data on a specific population or to develop new measures to collect data on a particular construct.

5. Practical gaps

These are gaps in the application of research findings to practical situations. For example, there may be a need for more research to understand how to implement evidence-based practices in real-world settings or to identify barriers to implementing such practices.

Examples of Research Gap

Limited understanding of the underlying mechanisms of a disease:.

Despite significant research on a particular disease, there may be a lack of understanding of the underlying mechanisms of the disease. For example, although much research has been done on Alzheimer’s disease, the exact mechanisms that lead to the disease are not yet fully understood.

Inconsistencies in the findings of previous research:

When previous research on a particular topic has inconsistent findings, there may be a need for further research to clarify or resolve these inconsistencies. For example, previous research on the effectiveness of a particular treatment for a medical condition may have produced inconsistent findings, indicating a need for further research to determine the true effectiveness of the treatment.

Limited research on emerging technologies:

As new technologies emerge, there may be limited research on their applications, benefits, and potential drawbacks. For example, with the increasing use of artificial intelligence in various industries, there is a need for further research on the ethical, legal, and social implications of AI.

How to Deal with Literature Gap?

Once you have identified the literature gaps, it is critical to prioritize. You may find many questions which remain to be answered in the literature. Often one question must be answered before the next can be addressed. In prioritizing the gaps, you have identified, you should consider your funding agency or stakeholders, the needs of the field, and the relevance of your questions to what is currently being studied. Also, consider your own resources and ability to conduct the research you’re considering. Once you have done this, you can narrow your search down to an appropriate question.

Tools to Help Your Search

There are thousands of new articles published every day, and staying up to date on the literature can be overwhelming. You should take advantage of the technology that is available. Some services include  PubCrawler ,  Feedly ,  Google Scholar , and PubMed updates. Stay up to date on social media forums where scholars share new discoveries, such as Twitter. Reference managers such as  Mendeley  can help you keep your references well-organized. I personally have had success using Google Scholar and PubMed to stay current on new developments and track which gaps remain in my personal areas of interest.

The most important thing I want to impress upon you today is that you will struggle to  choose a research topic  that is innovative and exciting if you don’t know the existing literature well. This is why identifying research gaps starts with an extensive and thorough  literature review . But give yourself some boundaries.  You don’t need to read every paper that has ever been written on a topic. You may find yourself thinking you’re on the right track and then suddenly coming across a paper that you had intended to write! It happens to everyone- it happens to me quite often. Don’t give up- keep reading and you’ll find what you’re looking for.

What is a ‘gap in the literature’?

The gap, also considered the missing piece or pieces in the research literature, is the area that has not yet been explored or is under-explored. This could be a population or sample (size, type, location, etc.), research method, data collection and/or analysis, or other research variables or conditions.

It is important to keep in mind, however, that just because you identify a gap in the research, it doesn't necessarily mean that your research question is worthy of exploration. You will want to make sure that your research will have valuable practical and/or theoretical implications. In other words, answering the research question could either improve existing practice and/or inform professional decision-making (Applied Degree), or it could revise, build upon, or create theoretical frameworks informing research design and practice (Ph.D Degree). See the Dissertation Center  for additional information about dissertation criteria at NU.

For a additional information on gap statements, see the following:

• How to Find a Gap in the Literature
• Write Like a Scientist: Gap Statements

How do you identify the gaps?

Conducting an exhaustive literature review is your first step. As you search for journal articles, you will need to read critically across the breadth of the literature to identify these gaps. You goal should be to find a ‘space’ or opening for contributing new research. The first step is gathering a broad range of research articles on your topic. You may want to look for research that approaches the topic from a variety of methods – qualitative, quantitative, or mixed methods. 

See the videos below for further instruction on identifying a gap in the literature.

Identifying a Gap in the Literature - Dr. Laurie Bedford

How Do You Identify Gaps in Literature? - SAGE Research Methods

Literature Gap & Future Research - Library Workshop

This workshop presents effective search techniques for identifying a gap in the literature and recommendations for future research.

Where can you locate research gaps?

As you begin to gather the literature, you will want to critically read for what has, and has not, been learned from the research. Use the Discussion and Future Research sections of the articles to understand what the researchers have found and where they point out future or additional research areas. This is similar to identifying a gap in the literature, however, future research statements come from a single study rather than an exhaustive search. You will want to check the literature to see if those research questions have already been answered.

Roadrunner Search

Identifying the gap in the research relies on an exhaustive review of the literature. Remember, researchers may not explicitly state that a gap in the literature exists; you may need to thoroughly review and assess the research to make that determination yourself.

However, there are techniques that you can use when searching in NavigatorSearch to help identify gaps in the literature. You may use search terms such as "literature gap " or "future research" "along with your subject keywords to pinpoint articles that include these types of statements.

Gaps in the literature.

Gaps in the literature are missing pieces or insufficient information in the published research on a topic. These are areas that have opportunities for further research because they are unexplored, under-explored, or outdated. 

Finding Gaps

Gaps can be missing or incomplete:

• Population or sample: size, type, location etc…
• Research methods: qualitative, quantitative, or mixed
• Data collection or analysis
• Research variables or conditions

Conduct a thorough literature search to find a broad range of research articles on your topic. Search research databases ;  you can find recommended databases for your subject area in  research by subject  for your course or program.

Identifying Gaps

If you do not find articles in your literature search, this may indicate a gap.

If you do find articles, the goal is to find a gap for contributing new research. Authors signal that there is a gap using phrases such as:

• Has not been clarified, studied, reported, or elucidated
• Further research is required or needed
• Is not well reported
• Suggestions for further research
• Key question is or remains
• It is important to address
• Poorly understood or known
• Lack of studies
• These findings provide valuable insights into the potential benefits of mindfulness-based interventions for stress management,however, further study is needed to address several limitations and extend our understanding in this area .
• While this study provides preliminary evidence of the potential efficacy of VRET in reducing PTSD symptoms, several aspects related to its implementation and specific treatment outcomes  remain inadequately clarified, highlighting the need for further research .
• Although the studies reviewed provide valuable insights into the potential effects of climate change on species composition and ecosystem functioning.  The question of how climate change will interact with other anthropogenic stressors to influence the resilience and adaptive capacity of tropical rainforest ecosystems remains unanswered, highlighting the need for further research .

Library Guide to Capstone Literature Reviews: Find a Research Gap

Find a research gap: tips to get started.

Finding a research gap is not an easy process and there is no one linear path. These tips and suggestions are just examples of possible ways to begin. 

In Ph.D. dissertations, students identify a gap in research. In other programs, students identify a gap in practice. The literature review for a gap in practice will show the context of the problem and the current state of the research. 

Research gap definition

A research gap exists when:

• a question or problem has not been answered by existing studies/research in the field 
• a concept or new idea has not been studied at all
• all the existing literature on a topic is outdated 
• a specific population/location/age group etc has not been studied 

A research gap should be:

• grounded in the literature
• amenable to scientific study
• Litmus Test for a Doctoral-Level Research Problem (Word) This tool helps students determine if they have identified a doctoral level research problem.

Identify a research gap

To find a gap you must become very familiar with a particular field of study. This will involve a lot of research and reading, because a gap is defined by what does (and does not) surround it.

• Search the research literature and dissertations (search all university dissertations, not just Walden!).
• Understand your topic! Review background information in books and encyclopedias . 
• Look for literature reviews, systematic reviews, and meta-analyses.
• Take notes on concepts, themes, and subject terms . 
• Look closely at each article's limitations, conclusions, and recommendations for future research. 
• Organize, analyze, and repeat! 

• Quick Answer: How do I find dissertations on a topic?

Start with broad searches

Use the Library Search (formerly Thoreau)  to do a broad search with just one concept at a time . Broad searches give you an idea of the academic conversation surrounding your topic.

• Try the terms you know (keywords) first.
• Look at the Subject Terms (controlled language) to brainstorm terms. 
• Subject terms help you understand what terms are most used, and what other terms to try.
• No matter what your topic is, not every researcher will be using the same terms. Keep an eye open for additional ways to describe your topic.
• Guide: Subject Terms & Index Searches: Index Overview

Keep a list of terms

• Create a list of terms
• Example list of terms

This list will be a record of what terms are: 

• related to or represent your topic
• synonyms or antonyms
• more or less commonly used
• keywords (natural language) or subject terms (controlled language)
• Synonyms & antonyms (database search skills)
• Turn keywords into subject terms

Term I started with:

culturally aware 

Subject terms I discovered:

cultural awareness (SU) 

cultural sensitivity (SU) 

cultural competence (SU) 

Search with different combinations of terms

• Combine search terms list
• Combine search terms table
• Video: Search by Themes

Since a research gap is defined by the absence of research on a topic, you will search for articles on everything that relates to your topic. 

• List out all the themes related to your gap.
• Search different combinations of the themes as you discover them 

For example, suppose your research gap is on the work-life balance of tenured and tenure-track women in engineering professions. In that case, you might try searching different combinations of concepts, such as: 

• women and STEM 
• STEM or science or technology or engineering or mathematics
• female engineering professors 
• tenure-track women in STEM
• work-life balance and women in STEM
• work-life balance and women professors
• work-life balance and tenure 

Topic adapted from one of the award winning Walden dissertations. 

• Walden University Award Winning Dissertations
• Gossage, Lily Giang-Tien, "Work-Life Balance of Tenured and Tenure-Track Women Engineering Professors" (2019). Walden Dissertations and Doctoral Studies. 6435.

Break your topic into themes and try combining the terms from different themes in different ways. For example: 

Theme 1 and Theme 4

Theme 2 and Theme 1

Theme 3 and Theme 4

Track where more research is needed

Most research articles will identify where more research is needed. To identify research trends, use the literature review matrix to track where further research is needed. 

• Download or create your own Literature Review Matrix (examples in links below).
• Do some general database searches on broad topics.
• Find an article that looks interesting.
• When you read the article, pay attention to the conclusions and limitations sections.
• Use the Literature Review Matrix to track where  'more research is needed' or 'further research needed'. NOTE:  you might need to add a column to the template.
• As you fill in the matrix you should see trends where more research is needed.

There is no consistent section in research articles where the authors identify where more research is needed. Pay attention to these sections: 

• limitations
• conclusions
• recommendations for future research 
• Literature Review Matrix Templates: learn how to keep a record of what you have read

How to Define a Research Problem | Ideas & Examples

Published on November 2, 2022 by Shona McCombes and Tegan George. Revised on May 31, 2023.

A research problem is a specific issue or gap in existing knowledge that you aim to address in your research. You may choose to look for practical problems aimed at contributing to change, or theoretical problems aimed at expanding knowledge.

Some research will do both of these things, but usually the research problem focuses on one or the other. The type of research problem you choose depends on your broad topic of interest and the type of research you think will fit best.

This article helps you identify and refine a research problem. When writing your research proposal or introduction , formulate it as a problem statement and/or research questions .

Table of contents

Why is the research problem important, step 1: identify a broad problem area, step 2: learn more about the problem, other interesting articles, frequently asked questions about research problems.

Having an interesting topic isn’t a strong enough basis for academic research. Without a well-defined research problem, you are likely to end up with an unfocused and unmanageable project.

You might end up repeating what other people have already said, trying to say too much, or doing research without a clear purpose and justification. You need a clear problem in order to do research that contributes new and relevant insights.

Whether you’re planning your thesis , starting a research paper , or writing a research proposal , the research problem is the first step towards knowing exactly what you’ll do and why.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

As you read about your topic, look for under-explored aspects or areas of concern, conflict, or controversy. Your goal is to find a gap that your research project can fill.

Practical research problems

If you are doing practical research, you can identify a problem by reading reports, following up on previous research, or talking to people who work in the relevant field or organization. You might look for:

• Issues with performance or efficiency
• Processes that could be improved
• Areas of concern among practitioners
• Difficulties faced by specific groups of people

Examples of practical research problems

Voter turnout in New England has been decreasing, in contrast to the rest of the country.

The HR department of a local chain of restaurants has a high staff turnover rate.

A non-profit organization faces a funding gap that means some of its programs will have to be cut.

Theoretical research problems

If you are doing theoretical research, you can identify a research problem by reading existing research, theory, and debates on your topic to find a gap in what is currently known about it. You might look for:

• A phenomenon or context that has not been closely studied
• A contradiction between two or more perspectives
• A situation or relationship that is not well understood
• A troubling question that has yet to be resolved

Examples of theoretical research problems

The effects of long-term Vitamin D deficiency on cardiovascular health are not well understood.

The relationship between gender, race, and income inequality has yet to be closely studied in the context of the millennial gig economy.

Historians of Scottish nationalism disagree about the role of the British Empire in the development of Scotland’s national identity.

Next, you have to find out what is already known about the problem, and pinpoint the exact aspect that your research will address.

Context and background

• Who does the problem affect?
• Is it a newly-discovered problem, or a well-established one?
• What research has already been done?
• What, if any, solutions have been proposed?
• What are the current debates about the problem? What is missing from these debates?

Specificity and relevance

• What particular place, time, and/or group of people will you focus on?
• What aspects will you not be able to tackle?
• What will the consequences be if the problem is not resolved?

Example of a specific research problem

A local non-profit organization focused on alleviating food insecurity has always fundraised from its existing support base. It lacks understanding of how best to target potential new donors. To be able to continue its work, the organization requires research into more effective fundraising strategies.

Once you have narrowed down your research problem, the next step is to formulate a problem statement , as well as your research questions or hypotheses .

Methodology

• Sampling methods
• Simple random sampling
• Stratified sampling
• Cluster sampling
• Likert scales
• Reproducibility

 Statistics

• Null hypothesis
• Statistical power
• Probability distribution
• Effect size
• Poisson distribution

Research bias

• Optimism bias
• Cognitive bias
• Implicit bias
• Hawthorne effect
• Anchoring bias
• Explicit bias

All research questions should be:

• Focused on a single problem or issue
• Researchable using primary and/or secondary sources
• Feasible to answer within the timeframe and practical constraints
• Specific enough to answer thoroughly
• Complex enough to develop the answer over the space of a paper or thesis
• Relevant to your field of study and/or society more broadly

Research questions anchor your whole project, so it’s important to spend some time refining them.

In general, they should be:

• Focused and researchable
• Answerable using credible sources
• Complex and arguable
• Feasible and specific
• Relevant and original

Your research objectives indicate how you’ll try to address your research problem and should be specific:

A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.

Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.

What is a research gap.

A research gap is a question or a problem that has not been answered by any of the existing studies or research within your field. Sometimes, a research gap exists when there is a concept or new idea that hasn't been studied at all. Sometimes you'll find a research gap if all the existing research is outdated and in need of new/updated research (studies on Internet use in 2001, for example). Or, perhaps a specific population has not been well studied (perhaps there are plenty of studies on teenagers and video games, but not enough studies on toddlers and video games, for example). These are just a few examples, but any research gap you find is an area where more studies and more research need to be conducted. Please view this video clip from our Sage Research Methods database for more helpful information: How Do You Identify Gaps in Literature?

How do I find one?

It will take a lot of research and reading.  You'll need to be very familiar with all the studies that have already been done, and what those studies contributed to the overall body of knowledge about that topic. Make a list of any questions you have about your topic and then do some research to see if those questions have already been answered satisfactorily. If they haven't, perhaps you've discovered a gap!  Here are some strategies you can use to make the most of your time:

• One useful trick is to look at the “suggestions for future research” or conclusion section of existing studies on your topic. Many times, the authors will identify areas where they think a research gap exists, and what studies they think need to be done in the future.
• As you are researching, you will most likely come across citations for seminal works in your research field. These are the research studies that you see mentioned again and again in the literature.  In addition to finding those and reading them, you can use a database like Web of Science to follow the research trail and discover all the other articles that have cited these. See the FAQ: I found the perfect article for my paper. How do I find other articles and books that have cited it? on how to do this. One way to quickly track down these seminal works is to use a database like SAGE Navigator, a social sciences literature review tool. It is one of the products available via our SAGE Knowledge database.
• In the PsycINFO and PsycARTICLES databases, you can select literature review, systematic review, and meta analysis under the Methodology section in the advanced search to quickly locate these. See the FAQ: Where can I find a qualitative or quantitative study? for more information on how to find the Methodology section in these two databases.
• In CINAHL , you can select Systematic review under the Publication Type field in the advanced search. 
• In Web of Science , check the box beside Review under the Document Type heading in the “Refine Results” sidebar to the right of the list of search hits.
• If the database you are searching does not offer a way to filter your results by document type, publication type, or methodology in the advanced search, you can include these phrases (“literature reviews,” meta-analyses, or “systematic reviews”) in your search string.  For example, “video games” AND “literature reviews” could be a possible search that you could try.

Please give these suggestions a try and contact a librarian for additional assistance.
