Question

Quizplus · Accepted Answer

Nonexperimental methods are appropriate when an experiment would not be ethical or possible, such as when manipulating certain variables could cause harm to participants or when the necessary conditions for an experiment cannot be created. Therefore, option A is the best choice. Option B is incorrect because nonexperimental methods typically have low internal validity, and option C is incorrect because nonexperimental methods can be used to test hypotheses (just not through manipulation of variables). Option D is also incorrect because nonexperimental methods do not establish causal relationships as strongly as experimental methods.
