How to Write a Research Question: A Complete UK Guide

Learning how to write a research question is an essential skill for UK university students. 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.

How to write a research question: Step-by-Step Guide

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.

Frequently Asked Questions

What is a research question?
A specific, answerable question that your dissertation or paper sets out to investigate.

What is the difference between a topic and a research question?
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.

Common Mistakes When Formulating a Research Question

One of the most frequent errors students make when developing a research question is selecting a topic that is far too broad. A question such as “What is the impact of social media on society?” is impossible to address rigorously within the constraints of a dissertation or thesis because it encompasses thousands of potential sub-topics across multiple disciplines. Effective research questions are bounded: they specify a population, context, time period, or phenomenon with enough precision that the scope of the investigation is clear from the outset. If your question could plausibly be answered in a dozen different ways depending on perspective, it needs to be narrowed further.

The opposite problem — excessive narrowness — also creates difficulties. A question that is too specific may leave you with insufficient literature to engage with, or may produce findings so contextually limited that they carry no transferable significance. The goal is to find a middle ground where the question is specific enough to be answerable but broad enough to connect with wider debates in your field. Your supervisor can help you calibrate this balance, and reading recently published dissertations in your subject area at your institution is an excellent way to develop a feel for appropriate scope.

Another common mistake is formulating a question that has already been definitively answered in the existing literature. Before committing to a research question, conduct a thorough literature search using databases such as JSTOR, Scopus, Web of Science, and your institution’s library catalogue. If the question has been exhaustively addressed, your task is to identify a gap: a population not yet studied, a geographical context overlooked, a time period not covered, or a theoretical framework not yet applied to the problem. Positioning your question in relation to this gap is what makes your research original and justifiable.

Aligning Your Research Question with Methodology and Objectives

A well-formulated research question does far more than define what you are investigating; it also determines how you will investigate it. The phrasing of your question signals the appropriate methodological approach. Questions beginning with “How many” or “To what extent” point towards quantitative methods, because they imply measurement and statistical analysis. Questions beginning with “How” or “Why” typically call for qualitative approaches, because they seek to understand processes, experiences, and meanings rather than to count or measure them. Mixed-methods designs may be appropriate where your question has both descriptive and interpretive dimensions.

Your research objectives should be derived directly from your research question. Objectives break the overarching question into discrete, achievable tasks that together constitute a complete answer. A typical dissertation might have three to five research objectives, each representing a stage in the investigation: reviewing the existing literature, collecting primary data, analysing findings, and drawing conclusions. The alignment between question, objectives, and methodology is something UK examiners scrutinise closely, and inconsistencies between these elements are a common source of examiner criticism in viva voce examinations.

It is worth revisiting your research question at several points during the research process. As your understanding of the literature deepens and your empirical work progresses, you may find that the original question needs to be refined. This is normal and does not represent a failure of planning; it reflects the iterative nature of rigorous scholarly inquiry. However, any significant changes to your research question should be discussed with your supervisor promptly, as they may have implications for your ethical approval, your data collection instruments, and ultimately the structure of your final submission. Keeping a transparent record of how and why your question evolved also makes for a more honest and credible methodology chapter.
