Question

Quizplus · Accepted Answer

One of the assumptions in ANOVA is the homogeneity of variances, which means that the population variances of the different groups being compared are equal. This assumption needs to be met in order for the F-test to be valid and accurate in determining whether there are significant differences between the group means. However, if this assumption is violated, there are alternative methods such as Welch's test or Games-Howell test that can be used to appropriately analyze the data.
