I recommended chi-square because your original post said that the data was in the form of percentages....correct?
- if so, I would not recommend ANOVA, since percentages are not normally distributed (they are bounded by 0% and 100%)
....a lack of normality doesn't usually throw off ANOVA results enough to worry about, but in this case, where they add up to 100%, ANOVA results may be very misleading....
