Hey all, I am currently working on the statistics part of my Master thesis and I am conducting an ANOVA test to compare mean variances between three samples. Four out of the 15 compared variables do not satisfy Levene's test for equality of variance. I know that ANOVA is relatively robust and most likely still offers valid results. Nonetheless, I will need to test the four variables for if they are truely different and I will have to choose and explain if and why ANOVA results are nonetheless valid. :yuck: How "safe" is ANOVA with these limitations and what test can I run (I am using SPSS 13 XP) to clarify the situation? Thanks a bunch!!
