Question

Quizplus · Accepted Answer

Experiments allow researchers to manipulate variables in order to determine cause-effect relationships, which is a strength not found in other research methods like surveys or observation studies. Double-blind methods and informed consent may be important in some experiments, but they are not inherent to the method itself. Correlations can be determined through other methods like surveys or observational studies, but again, cause-effect relationships are not necessarily determined through these methods.
