Deck 15: Analysis of Variance

Question 1

A comparison of the treatments based on independently selected experimental units that are randomly assigned to treatments is referred to as a completely randomized design.

Answer 1

True

Question 2

The fundamental identity for a single-factor ANOVA is MSTo = MSTr + MSE

Answer 2

False

Question 3

SSE measures the within-sample variability.

Answer 3

True

Question 4

Question 5

The P-value associated with the calculated F value in an ANOVA is the area to the right of the calculated value under an F distribution curve.

Question 6

As long as the other assumptions are plausible, the F test for testing the equality of population means in an ANOVA can be safely used when the largest sample standard deviation is no more than twice the smallest standard deviation.

Question 7

MSTr and MSE are statistics.

Question 8

SSE measures the within-sample variability.

Question 9

The P-value associated with the calculated F value in an ANOVA is the area to the right of the calculated value under an F distribution curve.

Question 10

The objective of a single-factor analysis of variance for k populations is to test the equality of the k population variances.
