Quizplus · Accepted Answer

Longitudinal studies involve tracking individuals or groups over an extended period of time, making them the best choice for examining changes in a person or group of people over time. Cohort studies track a specific group of individuals sharing a common characteristic, preexperimental studies are not as reliable as experimental studies, and historical control studies compare the results of an intervention group to data collected from a historical period where the intervention was not in place.
