Quizplus · Accepted Answer

The experimental method is the technique in which researchers manipulate independent variables and observe the effects on dependent variables to establish cause-and-effect relationships. Correlational research examines the relationship between variables, but does not manipulate them. Psychometric research focuses on the measurement of psychological phenomena. Case-studies are a type of observational research that involves the in-depth analysis of an individual or group.
