Understanding What ANOVA Post Hoc Tests Are, Really.
Homack, Susan R.
Many people use post hoc tests but do not completely understand why regular t-tests are not used post hoc or exactly what these tests are doing. This paper makes a direct comparison of Tukey and Scheffe post hoc tests with regular t-tests conducted using a new testwise alpha to make clear that controlling experimentwise error through some kind of Bonferroni-type correction is the basic concept underlying post hoc methods.
