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 interaction?     B1 B2 A1 11 19 A2 15 ?

A sample with M = 85 and s = 12 is transformed into z-scores.  After the transformation, what are the values for the mean and standard deviation for the sample of z-scores?

What value is estimated with a confidence interval using the repeated-measures t statistic?

With alpha = .05, what is the critical t value for a one-tailed, one sample t-test test with n = 15?

If other factors are held constant, what is the effect of increasing the sample variance?

A sample of n = 16 scores produces a one sample t-test statistic of t = 2.00.  If the sample is used to measure effect size with r2, what value will be obtained for r2?

The results of a two-factor analysis of variance produce df = 2, 36 for the F-ratio for factor A and df = 2, 36 for the F-ratio for factor B.  How many participants are in each of the treatment conditions?

The results of an independent-measures research study are reported as “t(20) = 2.12, p < .05, two tails." For this study, what t values formed the boundaries for the critical region?

A sample of n = 16 scores produces a one sample t-test statistic of t = 2.00.  If the sample is used to measure effect size with r2, what value will be obtained for r2?

If other factors are held constant, what is the effect of increasing the sample variance?
