Question

Quizplus · Accepted Answer

Epidemiological studies can observe and analyze correlations between factors, but they cannot prove causation without manipulation or experimentation. Therefore, choice A is incorrect. Epidemiological studies can find positive, negative, or no correlations, so choice B is incorrect. In vitro experimentation involves testing in a controlled laboratory environment, which is not typically involved in epidemiology studies, so choice D is also incorrect.
