If you think Im either stupid crazy or just plain nit-picking read on. The dependent variable must follow a normal distribution within each subpopulation. Therefore the ANOVA is robust to small deviations from the HOV assumption.

This refers to the assumption that group variances are roughly equal. If the assumption of homogeneity of variance has been violated Equal Variances Not Assumed the Games-Howell or.
