Upon completion of this activity, you will be able to:
· recognize the impact of violating statistical assumptions (e.g., normality, homogeneity of variance) in group comparison analyses;
· explain how violating assumptions when using ANOVA can lead to incorrect post hoc results;
· distinguish between commonly used post hoc tests (e.g., Bonferroni, Tukey, Games-Howell, Dunn’s) and identify when each is appropriate; and
· evaluate the importance of testing assumptions before selecting.
