The required condition for using an ANOVA procedure on data from several populations is that the sampled populations have equal variances. This is because ANOVA assumes homogeneity of variances, meaning that the variances of the populations being compared are equal. If equal variances are not present, the results of the ANOVA may be biased and unreliable. However, it is not necessary for the populations to have equal means or for the samples to be dependent on each other. Uniformity of the sampled populations is also not a requirement for ANOVA.
