Question

Quizplus · Accepted Answer

Experimental studies involve manipulating one variable (the independent variable) to see if it affects another variable (the dependent variable). This allows researchers to establish cause-and-effect relationships. Longitudinal studies track the same individuals over a long period of time, cross-sectional studies compare different groups at one point in time, and correlational studies examine the relationship between variables but do not determine causality.
