The p-value of a finding is the probability that the finding would have occurred by chance alone even if the null hypothesis is true. 

The following example in the form of a quiz may help clarify the definition.

If you were to conduct an experiment in which you asked both men and women to identify foods by smell, and found that women performed better, and after conducting a t-test, found that p<.05, what would this mean? [Note: These data are fictitious]
