If the independent variable does have an effect, then MSA should be MSError, and the resulting F statistic should be in a one-factor between-subjects analysis of variance.
A)smaller than; less than 1.00
B)nearly equal to; about 1.00
C)larger than; greater than 1.00
D)smaller than; greater than 1.00

If the independent variable has an effect, then the variability between the groups should be larger than the variability within the groups. This means that the MSA (mean square between-groups) should be larger than the MSError (mean square error). As a result, the F statistic (which is the ratio of MSA to MSError) should be larger than 1.00. Therefore, choice C is the best answer.

If the Independent Variable Does Have an Effect, Then MSA
