Heteroscedasticity

Muccatira, Devaiah M.
Hello.

I am running some group analyses using ANOVA and MANOVA statistics and am encountering high heteroscedasticity in my data, that is, I do not have homogeneity of variance between groups, making my statistic results less reliable.  Does anyone know how I might correct for this in my data such as performing some sort of transformation on my data values, or is there a more appropriate statistical method that I might use in this situation?  Thank you in advance.
