... For any experiment to be empirical, and therefore valuable, one must use the empirical scientific method. ... The experimental result is stated in terms of the functional relationship between the independent and dependent variable. ... Different experimental methods are used to control the variables, so that a direct relationship between the independent and dependent variables can be established. The experimental method is the only way one can establish cause-and-effect relationships. ...
