Which of the following is an advantage unique only to experiments?

A. Experimenters can observe and record information of interest.
B. Experimenters can use the data to draw cause-and-effect relationships.
C. Experimenters can reference sample data to draw inferences about the population.
D. Experimenters can work with a sample that represents the population as a whole.



Answer :

Final answer:

Experiments provide a unique advantage by enabling the establishment of cause-and-effect relationships through controlled experimental designs.


Explanation:

Experiments offer a unique advantage in that they allow researchers to establish cause-and-effect relationships. Through the use of controlled experimental designs, where subjects are randomly assigned to groups, researchers can attribute any differences to the conditions imposed on the experimental group, ensuring a solid basis for making claims about causality. This distinguishes experiments from observational studies, where the focus is on collecting rich, detailed information without the same level of certainty regarding causation.
