The scientific method requires that an hypothesis be ruled out or modified if its predictions are clearly and repeatedly incompatible with experimental tests further, no matter how elegant a theory is, its predictions must agree with experimental results if we are to believe that it is a valid description of nature. Scientific method examples of independent and dependent variables the variable deliberately changed in an experiment is known as the independent variable the dependent variable is the variable that may change as a result of changes in the independent variable.
