If a set of n = 9 difference scores has a mean of M_D = 3.5 and a variance of s² = 36,then the sample will produce a repeated-measures t statistic of t = 3.5/2.

Question

The repeated-measures t statistic is calculated as t = M_D / (s / √n), where M_D is the mean of the difference scores, s is the standard deviation of the difference scores, and n is the number of difference scores. In this case, M_D = 3.5, s = 6, and n = 9, so t = 3.5 / (6 / √9) = 3.5 / 2 = 1.75.
