By ueing Monte Carlo studies, this paper cornpaw the Welch test, the Jam-test and the Brown-Forsythe teat for comparing several means under heteroscedeeticity. It appeara that all the testa are quite robust with respect to departure from normality. The Brown-Foraythe test is at least as good as the
