Question

Quizplus · Accepted Answer

Experiments are the most valuable research method because they allow researchers to manipulate an independent variable and observe the effects on a dependent variable, thus establishing a cause-effect relationship. This is not possible with other research methods, such as surveys or case studies. Additionally, experiments often include control groups, which increase internal validity by ruling out alternative explanations for the observed effects. While choices A, B, and C are important features of experiments, they do not fully capture the unique value that experiments provide in establishing cause-effect relationships.
