The experimental design is the only research design that allows one to manipulate the independent variable to observe its effects on the dependent variable, thus establishing the cause-and-effect relationship. Case studies provide rich qualitative data but do not allow for generalizations or cause-and-effect inferences. Correlational designs show a relationship between variables, but it is not possible to determine which variable is causing the effect. Naturalistic observation involves observing behavior in a natural setting, but it is not possible to manipulate variables to establish cause-and-effect.
