Dear Michael, Thanks a lot for your concern, the reasons are as you have already said it as well as Nick, specially the fear of violating manova assumptions of normality and thus the danger of getting biased results. 2010/5/26 Michael N. Mitchell<Michael.Norman.Mitchell@gmail.com>:Dear Ama There have been some extremely useful answers to your question so far, and it might be completely settled. I don't know if anyone asked about the motivation for doing the non-parametric anova. I could see it being related to at least two different reasons... 1) The outcome variable is not measured on an interval scale (is ordinal). 2) There is question about meeting assumptions of the manova model, in terms of normality, homogeneity of variance, etc... especially if combined with small sample sizes. Perhaps letting us know about the underlying motivations for the selection of this model could help inform further useful information. Best regards, Michael N.

Any help would be highly appreciated.
