Question

Quizplus · Accepted Answer

A formal experiment allows researchers to manipulate an independent variable and observe the effects on a dependent variable, which provides the strongest evidence for cause-and-effect relationships. In contrast, case studies, correlational research, and descriptive surveys do not allow for manipulation of variables and therefore may not establish causal relationships.
