Whether you’re writing a research paper, thesis, or final year project in a Nigerian university, one of the most critical sections is your Method of Data Collection. This is where you show how you gathered the data used to analyze your topic or test your hypotheses.
Unfortunately, many students struggle to write this part properly, and that can lead to supervisor complaints, low grades, or even rejection of your work.
In this detailed guide, we will break down the methods of data collection for research in a way that’s clear, practical, and tailored for Nigerian academic requirements (undergraduate, postgraduate, or even diploma level).
What is Data Collection in Research?
Data collection refers to the process of gathering information from various sources to answer research questions, test hypotheses, or support your arguments.
It forms the foundation of your analysis and results. The quality of your data collection method determines how credible and valid your entire research will be.
Two Major Types of Data
Before choosing a data collection method, it’s important to understand the types of data you might be working with:
1. Primary Data
- First-hand data collected directly by you
- Typically gathered through surveys, interviews, focus groups, or experiments
- Example: Distributing questionnaires to students of UNILAG about online learning
2. Secondary Data
- Existing data collected by others
- Comes from books, journals, government reports, websites, or databases
- Example: Using NBS statistics or data from CBN reports
Common Methods of Data Collection in Nigerian Research
Let’s explore the most popular and acceptable methods in Nigerian universities (2025 standards):
1. Questionnaires
- A set of structured or semi-structured questions
- Can be administered physically (printed) or online (Google Forms, Microsoft Forms)
Best for:
- Quantitative research
- Large sample sizes
Advantages:
- Cost-effective
- Easy to analyze
- Anonymous responses encourage honesty
Disadvantages:
- Low response rates (especially for online surveys)
- Limited depth of answers
Example in research:
A survey of 300 SMEs in Lagos to determine the effect of digital marketing on business growth.
2. Interviews
- Can be structured (fixed questions) or unstructured (open-ended discussion)
- Conducted face-to-face, by phone, or virtually
Best for:
- Qualitative research
- Gaining deep insights or expert opinions
Advantages:
- Rich, detailed responses
- Allows for clarification and probing
Disadvantages:
- Time-consuming
- Data is harder to analyze
- Possible interviewer bias
Example:
Interviewing hospital managers in Abuja on challenges in public health delivery.
3. Focus Group Discussions
- 6–10 participants are interviewed as a group on a specific topic
- Facilitated by a moderator (you)
Best for:
- Exploring shared opinions
- Collecting multiple viewpoints
Advantages:
- Encourages idea generation
- Useful for exploring emerging trends
Disadvantages:
- Can be dominated by strong personalities
- Requires skilled moderation
Example:
Discussing the effects of ASUU strikes with final year students in UNN.
4. Observation
- Watching and recording behaviours or events as they happen
- Can be participant or non-participant
Best for:
- Studies involving human behaviour, workplace activity, etc.
Advantages:
- Captures real-time data
- Useful in natural settings
Disadvantages:
- Observer bias
- Ethical issues with covert observation
Example:
Observing customer behavior in a local supermarket to assess purchase patterns.
5. Document/Content Analysis
- Reviewing existing texts, records, videos, or social media content
Best for:
- Historical research
- Policy analysis
- Media studies
Advantages:
- Saves time and cost
- Provides access to authentic sources
Disadvantages:
- May be outdated
- Risk of misinterpretation
Example:
Analyzing CBN circulars from 2015–2025 to evaluate Nigeria’s monetary policy response.
Factors to Consider When Choosing a Data Collection Method
- Nature of your topic Quantitative topics usually require surveys; qualitative topics may use interviews or focus groups.
- Time & resources Can you afford to print 300 questionnaires? Or pay for Zoom interviews?
- Access to respondents Are your target participants easy to reach? Are they willing to answer?
- Ethical considerations Are you collecting sensitive information? Will you ensure anonymity?
- Supervisor’s preference or department guidelines Some Nigerian universities have strict formatting rules. Always check.
Tools That Can Help
- Google Forms – Free tool for creating online questionnaires
- MS Excel – For basic data entry and coding
- SPSS / STATA – For statistical analysis
- NVivo – For analyzing qualitative data
- Otter.ai – To transcribe interviews
- Grammarly – To edit your final report
Sample Write-Up for Method of Data Collection (You Can Use This)
This study employed the questionnaire method of data collection. A structured questionnaire was designed and distributed to 200 final-year students across three faculties in the University of Lagos. The questionnaire consisted of both closed-ended and open-ended questions. The choice of this method was influenced by the need to obtain quantitative data from a large sample size in a cost-effective and time-saving manner.
Common Mistakes to Avoid
- Using more than one method without justification
- Copying method sections from past projects without editing
- Failing to pilot your questionnaire or test your questions
- Leaving out ethical considerations
- Not explaining why you chose a specific method
Final Tips
- Always align your data collection method with your research objectives
- Back up your method choice with relevant citations (textbooks, journals)
- Clearly state your target population and sample size
- Don’t forget ethical approval if your school requires it
