How To Identify A Research Gap For Your Final Year Project

How to Identify a Research Gap for Your Final Year Project in Nigeria

A research gap is a specific question that existing studies have not answered well enough. It could be a group of people nobody has studied, a place with no recent data, two studies that disagree, or a method nobody has tried on your problem yet. When you find a real gap, you have more than a topic. You have a reason for your study, and that reason is what your supervisor and your defense panel will ask you to defend first.

Many students start the other way round. They pick a broad topic, then struggle to explain why it matters. It is easier to start with what is already known, look carefully at where that knowledge stops, and build your topic from that stopping point. This guide shows you how to do that in seven practical steps, with Nigerian examples you can adapt to your own department.

What Is a Research Gap, in Simple Terms?

Think of the literature on your topic as a conversation. Some questions have been answered clearly. Some have been answered only for one group, one place or one period. Some have been answered in ways that contradict each other. A research gap is the part of that conversation that is still open.

A gap is not the same as a topic. Your topic is the broad area, for example, social media and academic performance. Your gap is the missing piece inside that area, for example, how social media use during lectures affects the grades of part time HND students in polytechnics in Lagos State. The first is too wide for one project. The second names a population, a setting and a question you can actually study.

It is also not the same as saying nobody has ever studied your topic. That claim is hard to prove and easy for a supervisor to challenge with one search. A strong gap is built on what exists. You show what researchers already know, then you show clearly what they have not yet covered, and why filling that space matters.

The 7 Types of Research Gap to Look For

Knowing the names of the main gap types helps you describe your gap precisely, instead of writing vaguely that little research has been done.

• Population gap: The question has been studied, but not for your group. Most studies may cover university students in the United States, with nothing on ND students in Nigerian polytechnics, or on traders, nurses or small business owners in your state. Ask why your group might give a different answer, not just that it is missing.
• Context gap: Findings exist for one place or period, but not for yours. A study on remote work may cover Lagos banks in 2021, with no recent work on banks in Enugu or on staff in hybrid roles today. If the setting changes the result, the gap is worth studying.
• Evidence gap: Studies disagree. One finds that a teaching method improves scores, another finds no effect. Your project can test the same question with a clearer design or a different setting and help settle the disagreement.
• Methodological gap: Almost every study used the same method. If a topic has only been studied with questionnaires, an interview study could reveal why people behave the way the numbers suggest.
• Theoretical gap: A theory has not been applied to your problem, or two theories give different predictions. This type is common in postgraduate work, but undergraduates meet it too.
• Practical knowledge gap: What practitioners actually do differs from what the research recommends. You may have seen this during SIWES. If nurses, teachers or bank staff work in a way the literature does not describe, that difference can start a useful project.
• Time gap: The last serious study is old, and much has changed since then. A study on mobile banking from 2016 will not capture how students use fintech apps today, so an update can be a genuine gap, provided you can show what has changed.

For a final year project, population, context, methodological and time gaps are usually the most realistic. They build on established work, and they can be studied with the time, data and access a student actually has.

How to Identify a Research Gap in 7 Steps

Step 1. Start with a focused problem area, not a title

Choose an area you care about and can access. It could come from a course you enjoyed, a problem you saw during SIWES, or a question your supervisor mentioned in class. Write it in one sentence, for example, poor record keeping among small traders in Onitsha. Do not try to write a perfect title yet.

Step 2. Read recent review articles first

Start with review articles and systematic reviews. They summarise what is known and they often name open questions directly. Then read the most recent empirical studies, especially those from the last five years. Pay close attention to the introduction, where authors explain why their study was needed, and to the limitations and suggestions for future research, where authors often point to the next gap in plain language.

Step 3. Build a simple literature matrix

Make a simple sheet with columns for author and year, population, setting, method, main finding and stated limitation. After ten to fifteen studies, patterns start to show. You will see the same small samples, the same cities, the same method, or the same unanswered question appearing again and again. Empty cells and contradictions are your first candidates for a gap.

Step 4. Collect every future research suggestion you find

Keep a separate list of every sentence that says further research is needed or future work should examine a topic. Note the author and year beside each one. These are gaps named by experts, so they carry weight with a supervisor. Your job is to check whether anyone has already filled them since that paper was published.

Step 5. Look for contradictions and missing voices

Ask four questions as you compare studies. What remains unanswered? Which populations have received little attention? Do the findings agree or disagree? Have researchers relied on one method again and again? Also ask whose voice is missing. If all the studies interview managers and none interview junior staff or customers, that missing voice can be your gap.

Step 6. Write two or three candidate gaps in one sentence each

Turn each candidate into a single clear sentence. For example, no recent study has examined how WhatsApp based customer service affects repeat patronage among small fashion retailers in Aba. If you cannot state the gap in one sentence, it is still too broad.

Step 7. Test each candidate before you commit

Run a targeted search for each candidate, using several different keywords. If a recent study already answers it, drop that candidate and move to the next one. Then discuss the strongest candidate with your supervisor. A short conversation at this stage can save you weeks of rewriting later.

How to Test Whether Your Research Gap Is Real

Not every empty space is a useful gap. Run your candidate through these five checks before you settle on a topic.

• Is it specific? It should name a population, a setting, a variable and, where possible, a time period.
• Is it supported by recent literature? You should be able to cite two or three recent studies that show what is known and where it stops.
• Is it relevant? Filling it should change understanding, practice or policy in a clear way. Ask who benefits if you answer this question, and how.
• Is it feasible? Can you reach the respondents, get the data, and finish within your semester and budget?
• Is it still open? Check again with a fresh search just before you submit your proposal. A gap that was open in January may have been closed by a paper published in September.

Be careful with one common mistake. A single study that mentions a small sample does not automatically create a gap. Repeating a study with a slightly larger sample is rarely enough on its own. Your gap needs a clear reason, such as a different population, a new setting, a conflicting finding, or a method that can reveal something the earlier study could not.

Also phrase your claim carefully. Instead of writing that nobody has ever studied this, write that to your knowledge, no study has examined this question for this population in this setting, and show the search you did to support that claim. Supervisors respect that honesty, and it protects you at defense.

3 Nigerian Research Gap Examples You Can Learn From

Example 1. Business Administration

What is known: Several studies show that social media marketing increases sales for large retail brands in Lagos. What is missing: Very little work covers small fashion retailers in Aba who sell mainly through WhatsApp, with no physical shop and no paid adverts. Possible gap: Little is known about how WhatsApp based customer service affects repeat patronage among small fashion retailers in Aba, Abia State.

Example 2. Computer Science

What is known: Studies on e learning in Nigerian universities focus mainly on full time students and on whether the platform works. What is missing: Part time students, who study after work and rely on recorded lectures, are rarely studied separately. Possible gap: Existing studies give little attention to how recorded lectures affect the exam performance of part time undergraduates in Nigerian universities.

Example 3. Education

What is known: Research on teacher motivation often surveys teachers in urban public schools. What is missing: Teachers in rural private schools, who face different pay, workload and support conditions, appear far less often in the literature. Possible gap: The motivation of teachers in rural private secondary schools in Enugu State has received limited attention in recent research.

Notice the pattern in each example. The gap names what is known, what is missing, and who or where the missing work belongs to. That pattern makes it easy to move to the next step.

How to Turn Your Gap Into a Topic, Questions and Objectives

Once your gap is clear, the rest of Chapter One starts to fall into place. Use this order, because it keeps everything aligned.

1. Write your gap statement first. Use three parts: what is known, what is not known, and why it matters. Keep it to two or three sentences.
2. Turn the gap into a topic. Your topic should contain the main variables and the population or setting from your gap statement. Avoid adding extra variables that your gap does not support.
3. Write your research questions from the gap. Each question should ask about one part of the gap.
4. Write your objectives to match your questions. Use action verbs such as examine, assess, determine, identify and evaluate. One research question should produce at least one matching objective.
5. Check the alignment. Read your problem, gap, topic, questions and objectives together. They should tell one story.

Common Mistakes Students Make When Identifying a Research Gap

• Choosing a topic because it sounds new, without checking the literature. A quick search often shows that the question has already been answered.
• Confusing a personal interest with a research gap. Interest matters, but a gap must be shown in the literature, not just in your own curiosity.
• Claiming a gap after reading only two or three papers. Read widely enough to see the pattern. Ten to fifteen recent studies give you a much safer base than three.
• Picking a gap you cannot study. If you cannot reach the respondents or get the data, the gap is not suitable for your project.
• Writing the gap only in your proposal, then forgetting it. Your gap should run through your literature review, your methodology and your defense. The panel will ask whether you bridged the gap you claimed.

If you prepare with that last point in mind, defense becomes easier. You can already practise the question, did you bridge any gap from your study, using the list in the 25 most common project defense questions and answers on ProjectNG.

Frequently Asked Questions About Research Gaps

What is the difference between a research gap and a research problem?

A research problem is the broad issue your study addresses. A research gap is the specific missing piece of knowledge inside that issue. You start with the problem, find the gap through reading, and then build your study to fill that gap.

How many studies should I read before I claim a gap?

Aim for at least ten to fifteen recent and relevant studies for an undergraduate project, including two or three review articles where you can find them. The point is to read enough to see a pattern, not just to collect citations.

Can my research gap come from my SIWES or internship experience?

Yes, provided you can support it with literature. A practical problem you observed is a good starting point. Read around it, check whether researchers have already addressed it, and frame it as a gap only when the literature shows it is still open.

What if my supervisor says my gap is too broad or too narrow?

That is normal, and it is useful feedback. If it is too broad, narrow the population, the setting or the time period. If it is too narrow, widen one of those, or add a second variable that the literature also leaves open. Bring your literature matrix to the meeting, because it shows your supervisor exactly how you reached your gap.

Start With the Gap, and the Rest Becomes Clearer

Finding a research gap takes reading, patience and honest checking, but it saves far more time than it costs. It gives your topic a clear purpose, it makes your objectives and research questions easier to write, and it gives you a confident answer when your panel asks why your study matters.

Start with a focused area, read recent reviews and studies, map what you find, collect the future research suggestions, and test two or three candidates before you commit. When you can state your gap in one sentence, and support it with recent literature, you are ready to write your proposal and move into Chapter One with a topic you can defend.
