Answer #1

Assumptions for conducting an analysis of variance test or ANOVA includes the following

(A) Common variance

(B) Independence

(C) Normally distributed

Common variance means that the different samples must have same or common population variance in order to apply ANOVA for testing purpose

so, option A is only correct answer

We only same need equal variance, but not requiredment for ANOVA includes a maximum standard deviation of 100 or largest sample standard deviation is no more than twice the smallest

So, option B and C are incorrect
