How do you refine an RQ for analysis and evaluation?

Connecting the question to the topics context

  • Preliminary research helps you connect your question to a specific context, which refers to the background circumstances, time period or specific case study being investigated

  • Refining the question within a clear context ensures the Research Question (RQ)—the central question that directs the investigation—is focused and manageable within the 4,000-word limit

  • You should skim secondary sources—materials like journals or books that interpret and analyse primary data—to see how your topic fits into existing academic knowledge

  • This contextual connection acts as a springboard, allowing you to move from a broad interest to a specific, professional inquiry

Encouraging analysis evaluation and synthesis

  • Your refined question must be designed to trigger analysis rather than description

    • Analysis is the process of breaking down a topic to explore "why", "how" and "so what"

    • Description focuses only on stating the facts of "who", "what", "where" and "when"

  • The RQ should invite evaluation, which involves critically appraising the strengths and limitations of the evidence and research methods used

  • A strong question leads to synthesis—the ability to combine different research findings and perspectives to form a new, coherent conclusion

  • To ensure the essay is analytical, you should use higher-order questions, which typically begin with phrases such as "to what extent", "how significant" or "how successful"

Finalising the research question

  • The Research Question (RQ) should be finalised before you begin the stage of major research and data gathering

  • Settling on a clear question early prevents issues later on, such as realising the topic is unviable due to a lack of available data

  • Refining the question is an iterative process—a cycle of asking questions, taking action and reflecting—which should be tracked in the Researcher's Reflection Space (RRS)

    • The RRS is a personal journal or digital space used to record your thinking, mind maps and research decisions

  • Once the RQ is stable, it provides the foundation for a strong line of argument, which is the logical thread of reasoning that connects your question to your final conclusion

  • Aim to settle a clear provisional RQ before major research, but expect refinement as you read more

Examiner Tips and Tricks

Don’t be afraid to refine the wording. The IB explicitly recognises that changing direction (including amending the research question) can be completely acceptable as you read more.
