Quality depends on which aspect of the study?

• A. The amount of rigor (validity) that was used in conducting the study
• B. The number of authors
• C. The journal impact factor
• D. The funding source

Answer: (A)

Quality comes from how rigorously the study is designed and carried out, which determines the validity of its conclusions. A rigorous study uses appropriate design, proper controls, randomization and blinding when feasible, a sample size large enough to detect effects, valid and reliable measurement methods, and transparent, thorough reporting. These elements support internal validity (confidence that the observed effects are due to the studied factors) and external validity (whether findings generalize). Reliability of measurements—consistency across repeated measurements or studies—also matters for true quality. The number of authors, the journal’s prestige, or the funding source don’t by themselves guarantee quality; they can influence resources or perception, but the core measure of quality is the methodological rigor and the credibility of the conclusions drawn from the data.
