Research Questions

What Is a Research Question?

A research question is a clearly formulated inquiry that a researcher sets out to answer. It narrows a broad area of interest into a specific, testable or explorable focus. The research question governs the study's purpose, scope, and appropriate methodology. A vague or overly broad question leads to unfocused data collection, while an excessively narrow one may yield trivial findings. Careful formulation of the question is therefore one of the most critical early steps in any research process.

Types of Research Questions

Research questions fall into three main types. Descriptive questions aim to understand what a phenomenon is, how it is distributed, or what characteristics it has (e.g., "What are the academic stress levels of graduate students?"). Relational questions examine the association between two or more variables (e.g., "Is self-efficacy related to academic achievement?"). Causal questions investigate whether one variable influences another (e.g., "Does the intervention programme reduce anxiety levels?"). Each type calls for distinct research designs and analytical approaches.

FINER and PICO Frameworks

Researchers use structured frameworks to evaluate question quality. The FINER framework asks whether a question is Feasible, Interesting, Novel, Ethical, and Relevant. The PICO framework, widely used in clinical and health research, structures the question around Population, Intervention, Comparison, and Outcome components. These frameworks provide a systematic checklist to identify gaps or ambiguities before the study begins, helping the researcher enter the design phase with a well-grounded, clearly defined question that supports rigorous data collection and interpretation.

Common Pitfalls and Good Practice

Common mistakes in research question development include making the question too narrow to yield meaningful insight, incorporating unmeasurable concepts, or bundling multiple questions into one. A question such as "Does social media affect youth?" is inadequate because it leaves the platform, the population, and the type of effect undefined. A good question defines its key concepts, clarifies the context and scope of the study, and is answerable within available time and resources. Reviewing the question iteratively and seeking feedback from peers or advisors is the most effective path to a well-crafted, publication-ready research question.
