A researcher is interested in whether repeated experience with the Quantitative Reasoning portion of the GRE leads to better scores.Nine participants are recruited to a study in which each takes the GRE three times within a two-month period.Each participant agrees to not study during the times between tests.The data are as follows:
First test mean = 145
Second test mean = 146
Third test mean = 150
The researcher's graduate student is calculating the sums of squares for the data. Here is what he has so far:
SS experience = __________
SS subject = 2097
SS error = __________
SS total = 2296
1) Calculate SS experience.Show your work.
2) Calculate SS error.Show your work.
3) Compute the proper F statistic to test the null hypothesis that there is no effect of experience with the GRE on Quantitative test scores.Show your work.
