In a repeated-measures ANOVA, df within-treatment is calculated as (k-1)(n), where k is the number of treatment levels and n is the number of subjects. Given df within-treatment = 12 and n = 5, we can solve for k: (k-1)(5) = 12, so k-1 = 12/5 = 2.4, which is not possible. Therefore, the correct calculation should be for df error, which is (k-1)(n-1). Since df within-treatment is 12, and assuming a calculation error, df error should be (k-1)(5-1) = 8.
