A research gap is the missing or underexplored area in existing studies. Identifying it is one of the most important skills in academic research because it helps you develop original and valuable project topics.
What Is a Research Gap?
A research gap is an unanswered question or an area that has not been fully explored in existing literature. It forms the foundation of your study.
Why Research Gaps Are Important
- They make your study original
- They justify your research
- They guide your objectives
- They improve academic value
Without a gap, your project may lack direction.
How to Identify Research Gaps
1. Read Recent Journal Articles
Focus on publications from the last 5 years. Look at the “recommendations for future research” section.
2. Compare Different Studies
When multiple studies show conflicting results, there is likely a gap.
3. Check Limitations in Previous Research
Authors often mention what they did not cover.
4. Focus on Local Context
Many foreign studies exist, but local Nigerian contexts are under-researched.
5. Use Literature Reviews
Organize findings and identify what is missing.
6. Look for Outdated Data
If research was last conducted 10–15 years ago, it may need updating.
Types of Research Gaps
- Theoretical gaps
- Methodological gaps
- Population gaps
- Geographic gaps
- Data gaps
Example of a Research Gap
If many studies focus on urban areas, but few study rural communities, the rural area becomes your gap.
Conclusion
Research gaps are the backbone of academic writing. Once you master how to identify them, selecting a strong project topic becomes much easier.
4. Step-by-Step Guide to Narrowing Down a Broad Research Topic

Many students start with broad ideas like “education” or “business,” but supervisors expect a specific and focused topic. Narrowing your topic is essential for clarity and successful completion.
Why You Must Narrow Your Topic
A broad topic leads to:
- Confusion
- Weak objectives
- Poor methodology
- Difficulty in data collection
Step 1: Start With a General Idea
Example:
“Social media and business”
Step 2: Choose a Specific Area
Ask:
- Which type of business?
- Which platform?
Example:
“Instagram marketing for small businesses”
Step 3: Define Location or Population
Add context:
- Country
- City
- Age group
- Industry
Example:
“Instagram marketing for small businesses in Lagos”
Step 4: Define the Problem
What exactly are you studying?
Example:
“Effect of Instagram marketing on customer engagement in Lagos small businesses”
Step 5: Check Feasibility
Ensure:
- Data is available
- It is researchable
- It is not too wide
Step 6: Test with Your Supervisor
Always confirm before proceeding.
Common Narrowed Topic Example
Broad:
“Education and performance”
Narrow:
“Effect of study habits on academic performance of undergraduate students in University of Abuja”
Conclusion
Narrowing your topic helps you stay focused and increases your chances of approval. A precise topic leads to a stronger research project.
