The values in the following matrix are treatment means from a two-factor study. One of the means is missing. What value for the missing mean would most likely result in no main effect for factor A?     B1 B2 A1 6 12 A2 18 ?

One sample with n = 4 scores has a mean of M = 12, and a second sample with n = 6 scores has a mean of M = 8.  If the two samples are combined, what is the mean for the combined set of scores?

Two samples, each with n = 9 scores, produce an independent-measures t statistic of  t = 2.00.  If the effect size is measured using r2, what is the value of  r2?

For a particular sample, the largest distance (deviation) between a score and the mean is 11 points.  The smallest distance between a score and the mean is 4 points.  Therefore, the standard deviation ____.
