If an analysis of variance is used for the following data, what would be the effect of changing the value of M2 to 20?Sample DataM1 = 10    M2 = 15SS1 = 90    SS2 = 70

For a sample with s = 12, a score of X = 73 corresponds to z = 1.00.  What is the sample mean?

If other factors are held constant, how does sample size influence the likelihood of rejecting the null hypothesis and measures of effect size such as r2 and Cohen’s d?

Dr Gallimore notices that students that complete examinations early appear to receive the same grades as students that hang on to examinations until the last possible moment. The relationship between test score and exam time is an example of  _______________ .

Which combination of factors is most likely to produce a significant value for an independent-measures t statistic?

A sample has M = 72 and s = 4.  In this sample, what is the X value corresponding to z = –2.00?

One sample has a variance of s2 = 10 and a second sample has a variance of s2 = 6.  If the two samples have the same number of scores, what is the pooled variance for the two samples?
