Question

Quizplus · Accepted Answer

Epidemiological studies are designed to identify and point to potential causal factors of diseases by observing patterns, frequencies, and the distribution of health-related factors in populations. However, they often do not control for selection factors (variables that might influence the study's outcome), which is a limitation of such studies. This is because they are observational in nature and do not manipulate variables or conditions like experimental studies do.
