What Makes a Good Research Question?

The research question is the single most important element of any study. Everything that follows — your design, your sample, your analysis, your conclusions — flows from the question you ask. A vague question leads to a vague study. A clear question leads to a focused, impactful study. A good research question has several characteristics. It is specific — not 'Does exercise help?' but 'Does 30 minutes of daily walking reduce HbA1c in adults with type 2 diabetes over 12 weeks?' It is measurable — the outcome (HbA1c) can be objectively quantified. It is answerable — the study can actually be conducted with available resources, time, and participants. The FINER framework is a practical tool for evaluating research questions. F = Feasible (Can you actually do this study with your resources?). I = Interesting (Will the scientific community care about the answer?). N = Novel (Does this add something new to existing knowledge?). E = Ethical (Can this study be conducted ethically?). R = Relevant (Does the answer matter for clinical practice, policy, or science?). Common problems with research questions include being too broad ('What causes cancer?'), too narrow ('Does Brand X aspirin reduce headaches in left-handed women aged 35-36?'), not answerable ('Is surgery better than medicine?' — better at what, in whom?), or not novel (the answer is already well established). Refining a research question is an iterative process. Start with a rough clinical observation, search the literature to see what is already known, narrow down the population and outcome, and keep refining until your question is FINER-worthy.
