Quizplus · Accepted Answer

The degrees of freedom for the error term in a repeated-measures ANOVA should be calculated as (n-1)(k-1), where n is the number of participants and k is the number of conditions. With n = 7 and k = 4, the correct degrees of freedom for the error term should be (7-1)(4-1) = 18, not 21.
