What Makes a Good Research Question?

A research question defines the entire direction of your study. A poorly formed question leads to unfocused research and a weak paper. A strong research question is:

  • Focused: Narrow enough to be fully addressed within the scope of the project
  • Researchable: Can be answered through evidence and analysis (not purely opinion)
  • Complex: Requires more than a yes/no answer — demands analysis, evaluation or explanation
  • Significant: Worth asking — adds something to understanding of the topic
  • Clear: Unambiguous wording with no undefined terms

How to Develop Your Research Question

  1. 1

    Start with a broad topic and do preliminary reading

    Choose a general area of interest. Read introductory material to get an overview of the field and identify what is already known, what is debated and where gaps exist. Controversies, recent changes and under-studied populations are fertile ground for research questions.

  2. 2

    Narrow with the PICO or similar framework

    Use narrowing dimensions to focus your question. Ask: Who is affected or involved (population)? What is the specific issue, intervention or phenomenon (problem/focus)? What comparison is being made, if any? What outcome or effect are you examining? What is the timeframe or context? Adding 1–2 of these dimensions transforms a broad topic into a focused question.

  3. 3

    Test your question against quality criteria

    Is it too broad? (“How does social media affect people?” — too broad). Is it too narrow? (“How many Instagram posts did 14-year-old girls in Melbourne post in June 2023?” — too specific). Is it a yes/no question? (“Does exercise improve mental health?” — reframe as “What mechanisms explain the relationship between regular aerobic exercise and reduced anxiety symptoms in adults?”).

  4. 4

    Refine the wording

    Every word in a research question matters. Define terms that could be interpreted differently. Specify the population and context. Make the analytical relationship clear — “How does X affect Y in context Z among population P?” is a reliable structure.

Examples of refinementToo broad: “What is the effect of diet on health?” Better: “How does a Mediterranean diet affect cardiovascular disease risk factors in Australian adults over 50?” Too narrow: “How many calories did university students consume on Tuesdays?” Better: “What dietary patterns are associated with academic performance in first-year university students?”

Frequently Asked Questions

A research question asks what you want to find out (open-ended). A hypothesis is a specific, testable prediction about what you expect to find. Research questions are used in qualitative and exploratory research. Hypotheses are used in quantitative experimental research where you are testing a specific prediction. Many papers use a research question to frame the study and then derive specific hypotheses for testing within it.
Most undergraduate essays and research papers have one central research question, sometimes with 2–3 sub-questions that together address the main question. More than one central question usually indicates the scope is too broad or the paper is trying to do too much. For a thesis or dissertation, one primary question with supporting sub-questions is the standard structure.
