How to Write a Research Question
Learn how to write a research question by narrowing a topic, testing scope, choosing variables, examples, mistakes, troubleshooting, and FAQs.
Quick Answer
To write a research question, start with a broad topic, narrow it to a specific issue, choose a population, place, time, or relationship, make it answerable with evidence, and revise until it is focused enough for your assignment or study.
What You Need
- Assignment brief
- Topic idea
- Preliminary sources
- Target population or case
- Research method or evidence type
- Draft questions
Safety Precautions
- Follow academic integrity rules.
- Do not choose a question that requires private or harmful data collection without approval.
- Check whether human-subject research needs ethics review.
- Avoid questions that already assume the answer.
- Use credible sources to refine scope.
Step-by-Step Instructions
- Step 1
Start broad
Write your general topic in one phrase.
- Step 2
Narrow the topic
Add a group, place, time period, variable, or comparison.
- Step 3
Ask an open question
Use how, why, what effect, or to what extent when appropriate.
- Step 4
Check evidence
Make sure you can realistically find data or sources.
- Step 5
Check scope
Ask whether the question fits the word count, time, and method.
- Step 6
Remove bias
Avoid wording that assumes one answer is correct.
- Step 7
Revise after reading
Refine the question as your sources reveal what is feasible.
Practical Example
Example: Instead of asking “Is social media bad?” ask “How does nightly social media use affect self-reported sleep quality among college students?”
