Quizplus · Accepted Answer

Experiments allow researchers to compare groups, which is a key characteristic of an experimental study. Option A is incorrect because self-assignment into different groups can lead to selection bias and compromise the validity of the results. Option B is incorrect because while experiments can help researchers understand cause-and-effect relationships, they do not necessarily focus on participants' experiences. Option D is incorrect because all experiments face potential threats to validity, such as selection bias, instrumentation error, or maturation.
