Which statement best captures the role of a research question?

• A. It is the impetus behind research and guides every step and decision
• B. It is a mere formality with little impact on design
• C. It only sets the sample size
• D. It is derived after data collection

Answer: (A)

A research question acts as the driving force of a study, shaping its purpose, design, methods, and analysis. Because it defines what counts as evidence and what would count as an answer, the question determines what data to collect, how to collect it, what sample is needed, and which analyses will address the question. It is not just a formality or a afterthought, and it must be established before data collection to guide decisions and avoid biased or aimless work. The whole research plan—sampling, measurements, and ethical considerations—everything is aligned to answer that question. In short, the statement that the research question drives the research and guides every step and decision is the best description.
