A descriptive survey design simply means you ask a lot of people the same set of questions to describe what is happening — their opinions, habits, or experiences. You are taking a snapshot, not changing anything. It is the most common design in Nigerian undergraduate projects because it is practical: a questionnaire, a sample of respondents, and clear numbers at the end.
When to Use It
- You want to describe how common something is — attitudes, behaviours, levels of awareness.
- Your research questions start with "what", "how many", or "to what extent".
- You can reach a reasonable number of respondents with a questionnaire or short interview.
- You are not trying to prove that one thing causes another.
When Not to Use It
- You want to prove cause and effect — that is an experimental design.
- You need deep, detailed understanding of one organisation or person — use a case study.
- Your topic needs you to manipulate or control conditions.
Nigerian Project Example
"An assessment of social media usage among 200-level students of [University]." You distribute a questionnaire to a sample of students, then report percentages: how many use which platforms, how often, and for what. You are describing the situation, not testing a cause.
Undergraduate vs Postgraduate
Undergraduates usually run a single, straightforward survey of one population and report descriptive statistics. Postgraduates are expected to go further — larger or stratified samples, validated instruments, and often inferential tests linking the survey to a theory. The design is the same; the depth and rigour expected are higher.
Common Mistakes
- Claiming the survey "proves" a cause when it only describes a pattern.
- A vague population ("Nigerian students") that cannot be sampled properly.
- Leading or double-barrelled questionnaire items that push respondents to an answer.
- Too few respondents to say anything meaningful.

Frequently Asked Questions
Is a descriptive survey design quantitative or qualitative?
It is usually quantitative — you count responses and report numbers. It can include a few open-ended questions, but its core is describing patterns with statistics.
How many respondents do I need?
It depends on your population size. Use a sample-size method such as Taro Yamane — see our sample size determination guide.
