If you're searching for research question examples, sample research questions or a clear guide on how to make a research question, you're in the right place. Writing a good research question is one of the first - and most important - steps in any academic project. Whether you're working on an essay, dissertation or a full thesis, a clear research question gives your work direction, focus and purpose. It tells you what to look for, what to read and what your study is trying to answer.
But many students struggle with this step. Should your question be broad or narrow? How do you turn a simple topic into something researchable? What does a research question format look like? And what is a good research question example?
This guide breaks it down with simple steps, a clear research question format and 30+ research question examples for students, thesis writers and PhD researchers - all examples you can copy and adapt. By the end, you'll know how to write a research question that is clear, focused and ready for your supervisor's approval.
And if you want extra help brainstorming ideas or refining your final question, tools like ThesisAI can suggest variations, check clarity and help you test whether your question is research-ready.
What is a Research Question?
A research question is the clear, focused question your study will answer. It guides your reading, shapes your methods and defines the purpose of your project. A good research question is specific enough to explore in depth but open enough to allow analysis and discussion.
Think of it as the backbone of your research. Without a clear question, it's easy to get lost in your topic or collect information that doesn't actually help your study.
A strong research question should:
- Identify exactly what you want to find out
- Be researchable (not just based on opinion)
- Relate to a real academic problem or gap
- Give your project a clear direction
Whether you're writing a thesis, dissertation or a research essay, a good research question sets the stage for everything else you do.
If you need support choosing between multiple ideas or shaping a vague topic into a precise question, ThesisAI can help generate options, refine wording and test clarity.
Characteristics of a Good Research Question
A strong research question guides your entire project, so it needs to be more than "an interesting topic". A good research question has five key qualities:
- Clear: Easy to understand, with no vague terms
- Focused: Narrow enough to explore in an essay, dissertation or project
- Researchable: You can answer it using academic sources, data or analysis
- Specific: It tells the reader exactly what you want to investigate
- Aligned: Matches the goals of your course, assignment or thesis
If your research question meets these criteria, it becomes much easier to plan your literature search, choose your methods and stay on track throughout your project.
Types of Research Questions (With Examples)
When you start a project or thesis, choosing the right type of research question makes everything else easier - your literature review, your methods, and your analysis. Different questions are designed to explore different goals, so picking the right ones helps you stay focused and produce stronger academic research.
Below are the most common types of research questions, explained in simple terms with short examples you can borrow for your own work.
Descriptive Research Questions
Purpose: To describe something as it is.
Best for: Projects that measure trends, behaviors or characteristics.
Examples:
"What study habits do first-year university students use most often?"
"How many hours do medical students spend revising?"
Why it works: This type is clear, specific and measurable - key traits of a good research question.
Comparative Research Questions
Purpose: To compare two or more groups, conditions or approaches
Best for: Assignments that analyse differences
Examples:
"How do exam results differ between online and in-person learners?"
"Do students who use AI study tools revise more efficiently than those who don't?"
This creates a researchable question because the groups and variables are specific.
Causal Research Questions
Purpose: To explore cause-and-effect relationships
Best for: Experimental or statistical research
Examples:
"Does active recall improve long-term memory retention in psychology students?"
"Does using AI feedback tools lead to better essay grades?"
This is where research methods matter, you must be able to test the cause.
Exploratory Research Questions
Purpose: To explore a topic that is broad, new, or unclear
Best for: Early-stage research, dissertations, or areas with limited literature
Examples:
"How do students feel about using generative AI for academic writing?"
"What challenges do postgraduate students face when choosing a dissertation topic?"
These are ideal when you are still defining your specific topic.
Evaluative Research Questions
Purpose: To assess effectiveness or impact
Best for: Education, public policy, program evaluation
Examples:
"How effective is peer feedback in improving undergraduate writing?"
"How useful do students find ThesisAI when refining a research question?"
This creates a focused and strong research question with a clear outcome.
Correlational Research Questions (Relationships Between Variables)
Purpose: To examine relationships between variables without claiming causation
Best for: Statistical analysis or observational studies
Examples:
"Is there a relationship between study time and exam performance?"
"How does stress level relate to dissertation progress?"
These are quantitative and researchable, which works well for many thesis projects.
How to Turn a Topic Into a Research Question (Step-by-Step)
Turning a broad idea into a focused research question is one of the hardest parts of starting a thesis, but the process becomes simple once you follow a few clear steps. This section shows you how to turn a topic into a research question using a quick repeatable method. It also helps you with narrowing a research topic so your question becomes specific and researchable.
1. Start with a broad topic
Pick the general area you're interested in
Examples: social media, student wellbeing, AI in education.
2. Narrow the topic
Make it smaller by choosing a:
- Group (e.g. university students)
- Setting (e.g. online learning)
- Variable (e.g motivation, wellbeing)
Example: Social media → social media use among university students
3. Identify a problem or gap
Ask:
- What isn't fully known?
- What do researchers disagree about?
- What real issue needs exploring?
Example: Researchers disagree about whether social media helps or harms wellbeing
4. Turn it into a question
Use how/why/what:
- How does social media use affect students' wellbeing?
- Why do some students benefit while others feel stressed?
5. Test it
A good research question is:
- Clear
- Focused
- Specific
- Researchable
- Relevant
If it still feels broad, narrow it again.

Common Mistakes to Avoid
Before you finalise your idea, check for these common mistakes in research questions. These issues make it hard to produce a strong study, so use this list to evaluate a research question quickly:
- Too broad - The question covers too much and can't be answered in one project
- Too vague - Key terms are unclear or undefined
- Not researchable - You can't collect realistic data to answer it
- Yes/No questions - These lead to shallow answers with no analysis
- Not aligned with available data - You don't have access to the sources, people or information you'd need

FAQ: Research Question Examples, Format and Samples
What is a research question? (with example)
A research question is the focused question your study sets out to answer. It guides your reading, your methods and your analysis. Example: "How does AI-supported feedback affect writing performance in university students?" - that's a clear, researchable question with a defined group, variable and outcome.
What are 5 good research questions examples?
Five good research question examples across different fields:
- How does social media use affect stress levels in university students? (Psychology)
- Do remote-work policies improve employee productivity in small businesses? (Business)
- How does AI-supported feedback affect writing performance in high-school students? (Education)
- What barriers limit telehealth adoption among older adults? (Healthcare)
- How do AI study tools influence academic performance at university? (Technology)
How do you make a research question?
To make a research question, follow five steps: (1) pick a broad topic, (2) narrow it by group, setting or variable, (3) identify a gap or disagreement in the literature, (4) turn the gap into a how/why/what question, (5) test it against the criteria - clear, focused, specific, researchable and relevant.
What does a good research question format look like?
A good research question format usually follows: [How/Why/What] does [variable A] affect/relate to [variable B] in [specific group or setting]? For example: "How does sleep duration affect exam performance in first-year medical students?" The format keeps your question specific and researchable.
What is a PhD research question example?
A PhD research question is narrower and more original than an undergraduate one. Example: "How do generative AI tools shape epistemic agency in postgraduate research writing across STEM disciplines?" PhD research question examples typically combine an under-studied phenomenon with a defined theoretical lens.
What is a research question in a thesis?
A research question in a thesis is the central question your thesis answers - everything in the document (literature review, methodology, results, discussion) connects back to it. A strong thesis research question is focused enough to answer within your timeframe but important enough to justify the project.
Final Tips for Writing a Strong Research Question
A strong research question is the foundation of a great project. Once you know how to shape a clear, focused and researchable question, the rest of your thesis or dissertation becomes much easier to manage. Start small, stay curious and keep refining until your question feels solid.
