Explanation;
-Psychological studies vary in design. In correlational studies a researcher looks for associations among naturally occurring variables, whereas in experimental studies the researcher introduces a change and then monitors its effects.

Experiments establish cause and effect. A correlation identifies variables and looks for a relationship between them.
