Any time you reject a null hypothesis because a P value is less than your critical value, it's possible that you're wrong; the null hypothesis might really be true, and your significant result might be due to chance. A P value of 0.05 means that there's a 5% chance of getting your observed result, if the ...Post-hoc pairwise comparisons are commonly performed after significant effects when there are three or more levels of a factor.
