Question

Quizplus · Accepted Answer

Experimental methods involve manipulating one variable while keeping all other variables constant in order to determine causality. Observational methods involve simply observing and recording data without manipulating any variables. Correlational methods examine the relationship between variables but do not allow for cause-and-effect statements. Cross-sectional methods compare groups of individuals at a single point in time and do not manipulate any variables. Therefore, the best choice for making a valid cause-and-effect statement is the experimental method.
