when to use Games Howell

[L_Cai]

Dear Sir or Madame, 

I have performed Levene's Test for Homogeneity and Welch's ANOVA. If alpha is 0.05, then Levene's Test for Homogeneity is NOT met wile Welch's ANOVA is met. My question is: what kind of post hoc test should i choose? Games Howell?

You ought to have a look at box plots and diagnostic graphs.

"...Levene’s test or any other test for homogeneity of variance should not be used as a diagnostic for the assumption of equal group variances that underlies the usual analysis of variance..."
