Developing strong research questions

A good research question is essential to guide your research paper, project or thesis. It pinpoints exactly what you want to find out and gives your work a clear focus and purpose. All research questions should be:

  • Focused on a single problem or issue
  • Researchable using primary and/or secondary sources
  • Feasible to answer within the timeframe and practical constraints
  • Specific enough to answer thoroughly
  • Complex enough to develop the answer over the space of a paper or thesis
  • Relevant to your field of study and/or society more broadly

In a research paper or essay, you will usually write a single research question to guide your reading and thinking. The answer that you develop is your thesis statement — the central assertion or position that your paper will argue for.

In a bigger research project, such as a thesis or dissertation, you might have multiple research questions, but they should all be clearly connected and focused around a central research problem.

There are many types of research question that correspond to different types of research.

How to write a research question

The process of developing your research question follows several steps:

When you have a clearly-defined problem, you need to formulate one or more questions. Think about exactly what you want to know and how it will contribute to resolving the problem.

The way you frame your question depends on what your research aims to achieve. The table below shows some examples of how you might formulate questions for different purposes.

Research aims Research question formulations
Describing and exploring
  • What are the characteristics of X?
  • How has X changed over time?
  • What are the main factors in X?
  • How does X experience Y?
  • How has X dealt with Y?
Explaining and testing
  • What is the relationship between X and Y?
  • What is the role of X in Y?
  • What is the impact of X on Y?
  • How does X influence Y?
  • What are the causes of X?
Evaluating and acting
  • What are the advantages and disadvantages of X?
  • How effective is X?
  • How can X be achieved?
  • What are the most effective strategies to improve X?
  • How can X be used in Y?

Depending on the scope of your research, you may identify just one question or several. You may also have one primary research question and several secondary questions or sub-questions that relate to the same problem.

Example research problem Example research question(s)
The teachers at school X do not have the skills to recognize or properly guide gifted children in the classroom. What practical techniques can teachers at school X use to better identify and guide gifted children?
Under-30s increasingly engage in the “gig economy” instead of traditional full-time employment, but there is little research into young people’s experiences of this type of work. What are the main factors that influence young people’s decisions to engage in the gig economy? What do workers perceive as its advantages and disadvantages? Do age and education level have an effect on how people experience this type of work?

Most research questions can be answered with various types of research, but the way you frame your question should help drive your research design choices.

What makes a strong research question?

Writing questions isn’t a difficult task in itself, but it can be hard to work out if you have a good research question. Research questions anchor your whole project, so it’s important to spend some time refining them. The criteria below can help you evaluate the strength of your research question.

Focused and researchable

Criteria Explanation
Focuses on a single topic and problem Your central research question should follow from your research problem to keep your work focused. If you have multiple questions, they should all clearly relate to this central aim.
Answerable using primary or secondary data You must be able to find an answer by collecting quantitative and/or qualitative data, or by reading scholarly sources on the topic to develop an argument. If such data is impossible to access, you will have to rethink your question and ask something more concrete.
Does not ask for a subjective value judgement Avoid subjective words like good, bad, better and worse, as these do not give clear criteria for answering the question. If your question is evaluating something, use terms with more measurable definitions.

  • Is X or Y a better policy?
  • How effective are X and Y policies at reducing rates of Z?

Feasible and specific

Criteria Explanation
Answerable within practical constraints Make sure you have enough time and resources to do the research required to answer the question. If you think you might struggle to gain access to enough data, consider narrowing down the question to be more specific.
Uses specific, well-defined concepts All the terms you use in the research question should have clear meanings. Avoid vague language and broad ideas, and be clear about what, who, where and when your question addresses.

  • What effect does social media have on people’s minds?
  • What effect does daily use of Twitter have on the attention span of under-16s?
Does not ask for a conclusive solution, policy, or course of action Research is about informing, not instructing. Even if your project is focused on a practical problem, it should aim to improve understanding and suggest possibilities rather than asking for a ready-made solution.

  • What should the government do about low voter turnout?
  • What are the most effective communication strategies for increasing voter turnout among under-30s?

Complex and arguable

Criteria Explanation
Cannot be answered with yes or no Closed yes/no questions are too simple to work as good research questions — they don’t provide enough scope for investigation and discussion.

  • Has there been an increase in homelessness in the UK in the past ten years?
  • How have economic and political factors affected patterns of homelessness in the UK over the past ten years?
Cannot be answered with easily found facts and figures If you can answer the question through a Google search or by reading a single book or article, it is probably not complex enough. A good research question requires original data, synthesis of multiple sources, interpretation and/or argument to provide an answer.
Provides scope for debate and deliberation The answer to the question should not just be a simple statement of fact: there needs to be space for you to discuss and interpret what you found. This is especially important in an essay or research paper, where the answer to your question often takes the form of an argumentative thesis statement.

Relevant and original

Criteria Explanation
Addresses a problem relevant to your field or discipline The research question should be developed based on initial reading around your topic, and it should focus on addressing a problem or gap in the existing knowledge.
Contributes to a topical social or academic debate The question should aim to contribute to an existing debate — ideally one that is current in your field or in society at large. It should produce knowledge that future researchers or practitioners can build on.
Has not already been answered You don’t have to ask something groundbreaking that nobody has ever thought of before, but the question should have some aspect of originality (for example, by focusing on a specific location or taking a new angle on a long-running debate).

What can proofreading do for your paper?

Scribbr editors not only correct grammar and spelling mistakes, but also strengthen your writing by making sure your paper is free of vague language, redundant words and awkward phrasing.
