I am working on some data that is giving me fits. I have problems with
heterogeneity of variance. I have already omitted the outliers and have
tried every transformation in the book as well as weighted least squares.
The largest variance is associated with the smallest groups. My thought is
to do a nonparametric test - Kruskall-Wallis ANOVA. This of course does not
tell me where the difference is between by 7 means or mean ranks here now
with the K-W. My thought is to do the Games-Howell post hoc which assumes
heterogeneity of variance with my DV in ranks since that is the K-W does
ranks.
Does this sound reasonable or are there better ways to go about this?
Thanks!
