I. 1) 2) 3) 4) 5) MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. The analysis of variance is an inferential method that is used to test the equality of A) three or more population variances B) three or more population means C) two population variances D) two population means In general, how is the requirement of equal population variances veried? A) The largest sample standard deviation is less than or equal to the variance of the smallest sample. B) The largest sample standard deviation is equal to the sum of the other standard deviations. C) All three sample standard deviations must be equal. D) The largest sample standard deviation must be less than or equal to twice the smallest sample standard deviation. The One-Way-ANOVA hypothesis testing procedures assume equal population variances and independent samples.
