Research is a planned way of finding answers to a question using evidence. It is different from opinion because anyone can check how you reached the answer.
Why it matters
Good statistics cannot rescue a vague question. Knowing what research is helps you decide what to measure and how.
Key ideas
- Starts with a clear question
- Collects data in a planned, repeatable way
- Analyses the data with suitable methods
- Reports results honestly, including limits
Real-life research example
A nutrition researcher asks: "Does a school meal programme reduce anaemia in girls aged 10–14?" She plans who to measure, what to measure, and how to compare.
When to use
- You need an answer others can verify
- A decision (policy, treatment, teaching) depends on the answer
When NOT to use
- Don't call a quick poll of friends "research"
- Don't pick the method before the question is clear
Quick takeaway
Research = clear question + planned evidence + honest reporting.
Try it yourself
Write one research question from your own field. Then list what you would measure and on whom.
A good answer names the group (who), the measurement (what), and the comparison or relationship (what you want to know). Example: "Do girls in schools with meal programmes have higher mean hemoglobin than girls in schools without?"
