Groups means are compared two at a time to determine whether the difference between the pair of means is significant. Post-Hoc testing is a pairwise comparison. That type of testing is called Post-Hoc testing.
When this Null Hypothesis is rejected, further testing must be performed to determine which pairs of means are significantly different. ANOVA test the Null Hypothesis that all of the group means are the same.
