A type of study designed to answer the question of whether there is a causal relationship between two variables: whether changes in an iv cause changes in a dv. *sometimes not possible to have high validity in all four areas so researchers must prioritize which ones are most important. Most psychology studies have high internal and construct validity but sometimes sacrifice external validity manipulation of the iv: Manipulation of an iv must involve the active intervention of the researcher.
