The main difference between a correlational study and an experiment is that in an experiment, the investigator manipulates the independent variable, whereas in a correlational study there is no manipulation of variables. Correlational studies simply examine the relationship between two or more variables, while experiments seek to determine causation between variables by manipulating the independent variable and observing the effects on the dependent variable.
