In the analytic process, what is the purpose of the implicit question?

• A. To identify the disease etiology
• B. To measure overall incidence
• C. To ask whether there is an association between an outcome and a predictor, guiding further analysis
• D. To compute the case fatality rate

Answer: (C)

In the analytic phase, the central aim is to test whether there is a relationship between an exposure (predictor) and an outcome, and to use that question to guide what analyses to perform next. The implicit question asks whether an association exists, and the answer informs subsequent steps such as estimating measures of association and deciding on adjustments for confounding or exploring effect modification. If an association is found, you proceed with more rigorous modeling to understand its strength, direction, and robustness; if not, you may refine the exposure, outcome, or population or explore other predictors. This focus on association distinguishes it from purely descriptive tasks like counting incidence or case fatality, and from etiologic pursuits that aim to infer causality at a broad level.
