Describe one major advantage and one major disadvantage of experimental research designs

What will be an ideal response?

ANSWER:
?Experiments have several advantages. First, it is only through experimentation that we can approach two of the goals of psychology: explaining and changing behavior. An experiment is the only research method that enables us to determine cause- and-effect relationships. This advantage makes interpreting research results less ambiguous. In an experiment, we attempt to eliminate any confounding variables through experimenter control and random assignment of participants to groups. These techniques enable us to draw clearer conclusions from research results.

Experiments also have disadvantages. First, experiments do not address the first two goals of psychology: describing and predicting behavior. These are often the first steps in understanding behavior, and naturalistic observation, surveys, and correlational studies are quite useful for doing this. Second, in an attempt to control confounding variables, experiments conducted in laboratory settings may create an artificial atmosphere. It is then difficult to know whether the same result would occur in a more natural setting. This may be another reason to conduct naturalistic observations or correlational studies. Third, sometimes employing the experimental method is simply not possible for ethical or practical reasons.
