Learning how to write research questions means turning a broad area of interest into a single, clear, focused and answerable query that defines exactly what your study will investigate. In short: choose a broad topic, read around it, narrow it down, locate the gap, then draft a main question (plus sub-questions) that is specific, complex and feasible within your time and resources. This guide walks you through the full process step by step — the criteria a strong question must meet, the main types of research questions, a worked example you can copy, and a quick checklist to test your own — so you finish with a question that can genuinely carry a whole dissertation or research paper.
What is a research question?
A research question is a clear, focused and answerable query that identifies the main research problem or issue your research aims to address. It is the single most important sentence in your project: every chapter, every method and every source ultimately exists to answer it. A well-built research question does three jobs at once. It helps you:
- Define the scope of your study so you know what is in and what is out
- Guide your methodology and data collection choices
- Keep your writing aligned with your aims and objectives from start to finish
A strong research question does not only clarify your dissertation or research paper for your examiner; it also helps any reader grasp the purpose of your work in a single line. Get the question right and the rest of the project has a spine to hang on; get it wrong and you will feel the wobble in every chapter.
This guide is the how-to. If you want ready-made examples of research questions across subjects to model yours on, we keep a dedicated library of those; here we focus on the process of building your own.
What makes a strong research question?
Before you start drafting, it helps to know the target. Supervisors and markers tend to judge a research question against a small set of attributes. A good question contains only a single problem, can be answered using realistic primary and secondary data sources, fits within your time and word limit, can produce in-depth findings, and is genuinely relevant to your chosen field. The widely used FINER framework captures the same idea in five quick tests.
| FINER test | Ask yourself | Why it matters |
|---|---|---|
| Feasible | Can I actually collect this data with the time, access and skills I have? | Stops you promising fieldwork you can never finish. |
| Interesting | Does this genuinely intrigue me and my supervisor? | You will live with this question for months — motivation matters. |
| Novel | Does it address a gap rather than repeat settled findings? | Originality is what earns marks in higher-level work. |
| Ethical | Can it be answered without harming participants or breaching integrity? | An unethical question will never clear approval. |
| Relevant | Does answering it matter to your field or to practice? | Relevance is your justification in the introduction. |
If a draft question fails any one of these, reshape it before you go further. It is far cheaper to fix a question now than after you have collected the wrong data.
How to write a research question step by step
There is no single magic formula, but strong questions almost always emerge from the same six-step funnel. Work through them in order — each step narrows the one before it. Resist the temptation to leap straight to step five and invent a question on the spot: questions written before the reading is done almost always turn out to be too broad, already answered, or impossible to research. The early steps feel slow, but they are what make the final question defensible when your supervisor pushes back on it.
Step 1: Choose a broad topic
Every research journey begins with curiosity. Start by selecting a broad area of interest related to your field. At this first stage your dissertation topic should still be general; you will refine it later. It could be a subject you have studied, a social issue you care about, or a gap you have noticed in existing work. Ask yourself:
- What dissertation topics genuinely interest me?
- Is this topic relevant to my field, course or community?
- Are there enough credible academic sources available?
Step 2: Conduct preliminary research
Before you write anything, do some background reading to understand what has already been studied. This step helps you spot gaps, debates and unexplored corners within your topic. Review scholarly articles, reports and case studies, and search academic databases such as Google Scholar, JSTOR or your library catalogue. Take notes on recurring themes and points of disagreement. Good preliminary reading makes sure your eventual question is not repetitive and contributes something new.
Step 3: Narrow down your topic
A broad topic is too wide to study effectively, so the next move is to narrow it to a specific, researchable issue. You can tighten the focus along any of these dimensions:
- Population — e.g. first-year nursing students rather than “students”
- Geographical location — e.g. small firms in Manchester rather than “the UK”
- Time period — e.g. since the 2020 pandemic rather than “recently”
- A specific variable — e.g. staff retention rather than “performance”
A narrower topic gives you direction and makes the project realistic within your timeframe.
Step 4: Identify the problem or research gap
Once your topic is refined, pinpoint the problem or gap your study will address. A good research question almost always grows out of something unknown, contested or unresolved. A clear problem statement often leads naturally into the question itself. Probe your reading with three prompts:
- What do researchers still disagree about?
- What has not been studied deeply yet?
- What practical issue needs attention?
Step 5: Formulate the main research question
Now turn that gap into your primary research question — the core inquiry your whole project will answer. Keep it clear and concise, focused on a single issue, and answerable through realistic research. This main question defines the purpose of your study and shapes your research aims and objectives. A useful sentence stem is: “What is the effect of [variable A] on [variable B] among [population] in [context]?”
Step 6: Develop sub-questions
With your main question fixed, break it into two to four sub-questions. These split the central inquiry into smaller, manageable parts and let you explore different dimensions in detail. Each sub-question should address one unique aspect of the main topic; together they build a complete picture of your research problem and map neatly onto your dissertation chapters.
Worked example: from topic to finished question
The fastest way to see the funnel in action is to watch one real example move through all six steps.
- 1. Broad topic: Remote and hybrid working.
- 2. Preliminary reading: Plenty exists on productivity, but far less on employee wellbeing in small firms.
- 3. Narrowed focus: Hybrid working and wellbeing among employees of UK small and medium-sized enterprises (SMEs).
- 4. The gap: Most studies look at large corporations; SME staff are under-researched.
- 5. Main research question: “How does hybrid working affect the psychological wellbeing of employees in UK SMEs?”
- 6. Sub-questions:
- Which features of hybrid working (flexibility, isolation, blurred hours) most influence wellbeing?
- How do employees and line managers differ in how they perceive these effects?
- What support measures do SME employees say would improve their wellbeing?
The main question is single, complex (it needs “how”, not a yes/no), feasible with a survey and interviews, and clearly relevant — it passes every FINER test.
Types of research questions
Different types of research call for different styles of question. Knowing the category you are aiming for keeps your wording precise and tells your reader, at a glance, what kind of answer to expect. The table below maps the common approaches to the question shape each one uses.
| Question type | Typical formulation | Example |
|---|---|---|
| Descriptive | What are the properties or features of A? | What are the study habits of first-year UK undergraduates? |
| Comparative | What are the similarities and differences between A and B? | How do study habits differ between on-campus and online students? |
| Correlational | What is the relationship between variables A and B? | What is the relationship between sleep and exam performance? |
| Exploratory | What factors influence C? | Which factors shape graduates’ decision to freelance? |
| Explanatory | What causes C? How does B affect A? | Why do small firms struggle to retain graduate staff? |
| Evaluation | How effective is X at achieving Y? | How effective is a mentoring scheme at improving retention? |
Quantitative projects often lean on correlational and comparative questions, while qualitative projects lean on exploratory and explanatory ones. If your question hints at a measurable prediction, you may also need to turn it into a testable hypothesis before you design your study.
Main research question vs sub-questions
A common point of confusion is how the main question and the sub-questions relate. The main research question states the central problem; the sub-questions break that problem into the specific pieces you will actually investigate, one per chapter or theme. They should never wander off into a new topic — each must clearly serve the main question. A reliable test is to ask whether answering all of the sub-questions would, between them, fully answer the main one. If a sub-question could be deleted without leaving a gap, it is probably padding; if answering them all still leaves the main question half-open, you are missing one.
Keep two to four sub-questions as a rule of thumb. One sub-question usually means your main question was already narrow enough to stand alone; more than four often signals that your main question is doing the work of two separate studies and should be split.
| Main research question | Sub-questions | |
|---|---|---|
| Number | One | Two to four |
| Scope | The whole project | One dimension each |
| Purpose | Defines the study’s aim | Makes the aim achievable in steps |
| Where it appears | Introduction and conclusion | Methodology and findings chapters |
Common mistakes to avoid
Most weak questions fail for predictable reasons. Watch out for these:
- Too broad: “What causes poverty?” cannot be answered in one dissertation.
- Too narrow or factual: “How many students own a laptop?” is a single statistic, not a question worth a study.
- Yes/no questions: a strong question usually needs “how” or “why” so it demands analysis, not a one-word answer.
- Two questions in one: if you spot an “and” joining two issues, split it into a main question and a sub-question.
- Built on opinion, not evidence: questions you cannot answer with collectable data belong in an essay, not a research project.
- No clear link to a gap: if existing studies already answer it, there is nothing left to research.
“Formulating the research question is often the most difficult, and yet, most fundamental component of a research study.” — Farrugia et al., Canadian Journal of Surgery (2010)
How to test your research question
Once you have a draft, run it through a quick quality check before you commit. Three questions reveal most problems.
- Is it clear? Form the question only after finding a genuine gap, so it solves part of a real problem rather than restating a topic.
- Is it focused? The question should be specific and tied to the central aim of your study — if it could fit ten different dissertations, it is still too loose.
- Is it complex? It cannot be answered with a simple yes or no; it needs in-depth analysis and usually begins with “how” or “why”.
If your draft passes all three, it is ready to anchor your proposal and shape your methodology.

Final word
Writing a research question is really an exercise in narrowing: you move from a broad topic to a precise, answerable inquiry that sits on a clear gap in the literature. Follow the six steps, test your draft against the FINER criteria, and keep your sub-questions tightly tied to the main one. Whether the question will anchor a dissertation or a journal-style research paper, the time you invest at this stage pays back through every later chapter — a sharp question makes the writing, the method and the marking far easier.
One last habit worth keeping: treat your research question as a living draft until your proposal is approved. As you read more deeply, you may discover the gap is smaller than you thought, the data harder to reach, or the wording open to misreading. Revising the question at that point is not a sign of failure — it is the process working as intended. The students who struggle most are usually the ones who locked in a vague question early and then bent the whole project to fit it, rather than letting a clear question guide the project.
