**Statistics**

P = probability that rejecting the null hypothesis is due solely to chance factors. What is your null hypothesis? If Ho = no difference, then I would agree with you.

**experimental psychology**

Have questionnaires for subjects to explore these phenomena or have behavioral criteria that allow one to infer these phenomena.
