Quizplus · Accepted Answer

The within-samples degrees of freedom for an ANOVA is calculated as N - k, where N is the total number of observations and k is the number of groups. Here, N = 3 groups * 5 observations/group = 15, and k = 3. Therefore, the within-samples degrees of freedom = 15 - 3 = 12.
