How to write a research question

A good research question names what you will study, in whom, where and when, and asks something your study can actually answer. Start from a topic, narrow it to a problem, then write a question whose type (descriptive, comparative, relational, explanatory and so on) fits what you want to find out. Test it against the FINER criteria: feasible, interesting, novel, ethical and relevant.

Why the question comes first

The research question decides almost everything that follows: what data you need, from whom, how you collect it and how you analyse it (Creswell & Creswell, 2018; Punch, 2005). A vague question leads to a study that collects too much, analyses the wrong thing, or can't reach a conclusion. A clear one tells you, and your reader, what the study is for.

Writing a good question usually takes several drafts. That is normal: refining the question is part of the research, not a delay before it.

From topic to question

  1. Topic: the broad area you are interested in, such as tourism in Nepal.
  2. Problem: something specific that is unknown, contested or causing difficulty, such as whether income from homestays reaches poorer households.
  3. Aim: what your study will do about the problem, such as examine how homestay income is distributed.
  4. Question: the specific question your study will answer, naming its variables or concepts, its population, its setting and, where it matters, its time.

Reading the literature as you go keeps the question honest: it shows what is already known, so you don't ask a question that has been answered, and it supplies the concepts and measures you will use.

What a research question names

Most research questions name some of these elements; which ones a question needs depends on its type. The examples are the elements the Research Question Builder finds in the refined question in the worked example below.

ElementWhat it isExample
Independent variableWhat you think influences or explains something elseparticipation in a homestay programme
Dependent variableWhat you measure as the outcomehousehold income
PopulationWho or what the study is abouthouseholds
ContextWhere, or in what settingGhandruk
TimeWhen, where it mattersin 2024

A qualitative question usually has no independent and dependent variables: it names a phenomenon or experience to explore, the people who experience it and the setting.

Types of research question

Questions can be classified by purpose (what they ask) and by approach (how they will be answered). The Research Question Builder uses these types, each with an example from its knowledge base:

Types of research question Scroll sideways to see every column.
TypeWhat it asksExample
DescriptiveAsks what something is like: how common, how much, or what its characteristics are.What is the level of physical activity among office workers in Leeds?
ComparativeAsks how two or more groups, places or times differ on something.How does reading attainment differ between pupils in rural and urban schools?
RelationalAsks whether and how two or more things are related.What is the relationship between screen time and sleep quality among teenagers?
CorrelationalAsks whether two measured variables vary together, and how strongly.To what extent are working hours associated with burnout among junior doctors?
ExplanatoryAsks why something happens, or how one thing influences another.How does peer mentoring influence retention among first-year students?
ExploratoryAsks how people experience or understand something, usually where little is known.How do newly qualified teachers experience their first term?
PredictiveAsks whether one or more factors can predict a later outcome.To what extent do first-year grades predict final degree classification?
QualitativeA question answered with words, observations or images, focusing on meanings, experiences and processes.In what ways do carers describe their access to respite care?
QuantitativeA question answered with numerical data, asking how much, how many or how strongly.How many hours of paid work do full-time students do each week?
Mixed methodsA question with a quantitative and a qualitative part, answered by combining both kinds of data.To what extent does flexible working affect job satisfaction, and how do employees explain the effect?

An explanatory question asks about causes, and answering it convincingly needs a design that can support causal claims, such as an experiment, or careful reasoning about other explanations. A relational question claims less, and is easier to answer with survey data.

Test it: the FINER criteria

The FINER criteria are a widely used checklist for a research question (Hulley et al., 2013):

The FINER criteria Scroll sideways to see every column.
CriterionAsk yourself
FeasibleCan you answer it with the time, access, skills and resources you have?
InterestingDoes the answer matter to you, your supervisor and people in your field?
NovelDoes it add something new: new evidence, a new setting, or a new way of looking at the problem?
EthicalCan it be answered without undue risk to participants, researchers or communities?
RelevantWill the answer serve your aim and matter to your field, to practice or to policy?

Only some of these can be judged from the wording. Whether a question is interesting or novel depends on the literature and on your field, so discuss it with your supervisor.

Worked example: refining a broad question

This is a hypothetical example of how a student might refine a question; it doesn't describe a real study.

Refining a question in three drafts Scroll sideways to see every column.
DraftQuestionProblem or improvement
1How does tourism affect Nepal?Far too broad: no population, no measurable outcome, and no study could answer it
2Do homestays help people in Ghandruk?A yes/no question with a vague outcome: “help” and “people” need defining
3What is the relationship between participation in a homestay programme and household income among households in Ghandruk, Kaski district, in 2024?Relational, with an independent variable, a dependent variable, a population, a context and a time; answerable with a household survey

The third draft could be complemented by a qualitative question, such as “How do households in Ghandruk describe the benefits and costs of running a homestay?”, which would make it a mixed-methods study. Check draft 3 against FINER: feasibility depends on reaching enough households; ethics on how income questions are asked and kept confidential.

Try it: weak or improved?

Think about what is wrong with each question below, then open it to compare. The examples are invented for practice.

A question about social media and students

Weak: Is social media bad for students?

Improved: Is the time undergraduate students in Kathmandu spend on social media each day associated with their self-reported sleep duration?

“Bad” is a judgement, not a measurable outcome, and “students” and “social media” are too broad to study. The improved version names the variables, the population and the setting.

A question that can be answered yes or no

Weak: Do homestays help communities?

Improved: How does participation in a homestay programme relate to household income in Ghandruk?

A yes or no question hides the real interest, which is how and how much. The improved version states the relationship to be examined and where.

Main questions, sub-questions and objectives

Larger projects, such as a dissertation, usually have one main question and a few sub-questions that together answer it. Each sub-question should be answerable in its own right and needed for the main question. Research objectives restate the questions as tasks, one objective for each thing the study must do.

In quantitative research, a question about relationships or differences often leads to hypotheses: testable predictions about what the answer will be.

Common mistakes

  • Too broad: a question a whole field couldn't answer, let alone one study.
  • Too narrow or already answered: a question with an obvious or published answer.
  • Yes/no wording, which invites a one-word answer; “to what extent”, “how” and “what is the relationship between” open it up.
  • Two questions in one, joined by “and”, which may need different designs.
  • Vague terms such as “impact”, “success” or “development” that can't be observed or measured as written.
  • A conclusion built in, such as “Why does social media harm students?”, which assumes the answer.
  • A causal question (“effect of”) for a study that can only show association.
  • A question that isn't feasible with the access, time or data available.

Checklist

  • It names what you will study, in whom, where and, if it matters, when.
  • Its type matches what you want to know, and your design can answer it.
  • Its key terms can be defined and, for a quantitative question, measured.
  • It doesn't assume its own answer.
  • It passes the FINER criteria, including feasibility.
  • Your objectives, design and analysis follow from it.

Build your question with ResearchKit

The Research Question Builder identifies your question's type and elements, flags what is missing, and walks you through the FINER criteria, saying which ones only you can judge. From there, the Research Objectives Generator turns the question into objectives and the Hypothesis Builder into testable hypotheses.

Frequently asked questions

How long should a research question be?

Long enough to name its key elements, usually one sentence. If it needs two sentences, it may be two questions.

Should it be a question or a statement?

A question, ending with a question mark. Aims and objectives are written as statements.

How many research questions should I have?

It depends on the project and your institution's expectations. A dissertation usually has one main question and a few sub-questions; check your handbook.

Can my question change during the research?

In exploratory and qualitative research it often does, as you learn more. In a quantitative study, fix it before collecting data, and report any change honestly.

What makes a question qualitative or quantitative?

What answering it needs: numbers and measurement, or words, meanings and experiences. Some questions need both.
