If a set of n = 9 difference scores has a mean of MD = 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 = MD / (s / √n), where MD is the mean difference, s is the standard deviation, and n is the sample size. In this case, MD = 3.5, s² = 36, and n = 9, so s = √36 = 6. Therefore, t = 3.5 / (6 / √9) = 3.5 / 2 = 1.75.
