The within-groups degrees of freedom are calculated as (n - 1) * k, where n is the number of participants in each group and k is the number of groups. In this case, n = 5 and k = 4, so the within-groups degrees of freedom are (5 - 1) * 4 = 16. The between-groups degrees of freedom are calculated as k - 1, where k is the number of groups. In this case, k = 4, so the between-groups degrees of freedom are 4 - 1 = 3.
