A strong research question is the foundation of every dissertation, thesis and research paper — get it right and the whole project becomes easier; get it wrong and you struggle for months. UK supervisors consistently say a focused, researchable question is the single best predictor of a smooth project. This complete guide explains what makes a good research question, the difference between a topic and a question, how to use frameworks like FINER and PICO, and how to refine your question.
Topic vs Research Question
A topic is a broad area (“social media and mental health”). A research question is a specific, answerable question within it (“How does daily Instagram use relate to anxiety levels among UK undergraduates?”). Your whole project answers the question, not the topic.
What Makes a Good Research Question?
✓ Focused — narrow enough to answer within your scope.
✓ Researchable — answerable with available data and methods.
✓ Specific — clear about who, what and where.
✓ Significant — worth investigating and adding to knowledge.
✓ Feasible — achievable in your time and resources.
The FINER Criteria
A useful test is FINER: Feasible, Interesting, Novel, Ethical, Relevant. If your question fails any of these — for example it cannot be answered ethically, or has already been thoroughly settled — refine it before you commit.
Using PICO for Health Research
For clinical and health questions, the PICO framework helps: Population, Intervention, Comparison, Outcome. It turns a vague clinical interest into a precise, answerable question and is widely used in nursing and medicine.
Refining Your Question
Your first question is almost always too broad. Narrow it by population, time, place or variable until it is genuinely answerable. Read around the topic first — a good question often emerges from spotting a gap in existing research. See our research proposal guide.
Common Mistakes to Avoid
✓ A question that is too broad or too vague.
✓ A simple yes/no question with no depth.
✓ A question that cannot be answered with available data.
✓ One that has already been fully answered.
✓ Confusing the topic with the question.
Tips for a Strong Question
Read widely before deciding, use FINER or PICO to test it, make it specific and feasible, and be willing to refine it as your reading develops.

A topic is a broad area; a research question is a focused, answerable question within it.
What makes a good research question?
It is focused, researchable, specific, significant and feasible.
What is the FINER criteria?
A test of whether a question is Feasible, Interesting, Novel, Ethical and Relevant.
What is PICO?
A framework for clinical questions: Population, Intervention, Comparison, Outcome.
How many research questions should I have?
Often one main question with a few sub-questions; check your brief.
Can a research question be a hypothesis?
They are related; a hypothesis is a testable prediction often derived from a research question.
How do I narrow a broad question?
Limit it by population, time, place or variable until it is answerable in your scope.
How long should a research question be?
One clear sentence is usually best, sometimes with short sub-questions.
How do I know my question is researchable?
You can answer it with data and methods available to you within your time and resources.
