Models and Theories

There are four questions to be asked of any theory?





1) What is being measured? (i.e. what are the variables?)

2) What is being assumed and why? (i.e. what are the assumptions?)

3) What statement is being made about the variables? (i.e. what is the hypothesis?)

4) What is predicted? (i.e. what are the predictions?)
 
 

If these four questions cannot be answered satisfactorily, one is not using a theory.
Be sure you are working with a theory.
