Question

If the results of an experiment using a one-factor between-subjects analysis of variance were summarized as F(2, 12) = 2.24, p > .05, then you know that the experiment used subjects and the Fobs was.
A)12; statistically significant
B)15; statistically significant
C)12; nonsignificant
D)15; nonsignificant

Quizplus · Accepted Answer

The notation F(2, 12) indicates that there were 2 degrees of freedom between groups and 12 degrees of freedom within groups, which suggests there were 15 subjects in total (since degrees of freedom within groups are calculated based on the total number of subjects minus the number of groups). The F observed (Fobs) value of 2.24 with a p-value greater than .05 indicates that the result is nonsignificant, meaning there is not enough evidence to suggest a difference between the groups.
