Question

For an analysis of variance comparing four treatment means with a separate sample of n = 8 participants in each treatment, the F-ratio will have df = 3, 31.

Answer 1

Answer: False

Step-by-step explanation:

To get the F-ratio, we make use of the degree of freedom of sum of square treatment and sum of square error.

D.F for SStreatment = t - 1 = (4-1) = 3

D.F for SSerror = N - t = (32-4) = 28

Where t is the number of treatment, N is the total number of samples (8×4=32)

Thus, the right degree of freedom for the F-ratio is DF= 3, 28.
