What is the critical value for factor A in a Factorial ANOVA with N=25, 4 levels for factor A and 5 levels for factor B, and an alpha level of 0.05?

Assuming that there is a 5-point difference between the two sample means, which set of sample characteristics is most likely to produce a significant value for the independent-measures t statistic?

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

For a sample with M = 50 and s = 12, what is the X value corresponding to z = –0.25?

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?
