Which of the following is NOT an assumption of an independent-measures ANOVA?

A sample of n = 5 scores has a mean of M = 8.  One new score is added to the sample and the new mean is calculated to be M = 9.  What is the value of new score?

A sample of n = 5 scores has a mean of M = 12.  What is ΣX for this sample?

In an independent-measures ANOVA, individual differences contribute to the variance in the numerator and in the denominator of the F-ratio.  For a repeated-measures ANOVA, what happens to the individual differences in the denominator of the F-ratio.

For an independent-measures research study, the data show an 8-point difference between the two treatment means and a pooled variance of 4.  Given this information, what is the value of Cohen’s d?

An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment.  For this study, the three sample means are, M1 = 1,  M2 = 2,  and M3 = 3.  For the ANOVA, what value would be obtained for SSbetween?
