Why do quasi-experiments tend to have very good construct validity for the independent variable?
A)The manipulations have been previously validated in the lab.
B)They use real-world manipulations/experiences.
C)They tend to use more participants.
D)They also have good construct validity for the dependent variable.

Question

Quizplus · Accepted Answer

Quasi-experiments are studies where the independent variable occurs naturally, instead of being manipulated by the researcher. As a result, the manipulation is often a real-world manipulation or experience, which increases the construct validity of the independent variable. Therefore, option B is the correct answer. Option A may be true in some cases, but not necessarily in all quasi-experiments. Option C is irrelevant to the construct validity of the independent variable. Option D is not necessarily true - quasi-experiments may have poor construct validity for the dependent variable if the measurement is not well-designed.
