Question

Quizplus · Accepted Answer

Manipulation of variables is the key ingredient that sets experimental studies apart from assessment studies. In experimental studies, researchers manipulate one or more variables to observe the effect on a dependent variable. Assessment studies, on the other hand, do not involve manipulation of variables. Options A and B are not necessarily distinguishing factors between experimental and assessment studies, as both types of studies can involve animals or retrospective data. Option D could be present in both types of studies, as observation and assessment of behavior can be done in experimental and assessment studies alike.
