In an analysis of variance with a between-groups population variance estimate of 30 and a within-groups estimate of 25,the F ratio is
A)25 / (30-25)= 5.00
B)(30-25)/ 30 = 0.17
C)25 / 30 = 0.83
D)30 / 25 = 1.20

Quizplus · Accepted Answer

The F ratio is calculated by dividing the between-groups variance estimate by the within-groups variance estimate, which is 30 / 25 = 1.20.
