Explain what would happen to the F ratio of this analysis of variance if 2 points were added to each score in Finals only group?  (Note:  The new scores would be 2, 4, 2, and 4 with T = 12 and SS = 4.)

(Use this data to answer questions 18-20). A psychologist would like to examine the effects of different testing methods on the final performance of college students. One group has regular quizzes, one group has three large exams, and the third group only has a final exam. At the end of the course, the psychologist interviews each student to get a measure of the student's overall knowledge of the material. The results were as follows: Quizzes Exams Final Only. G = 48 ΣΧ2 = 272 F 574 00 3674 ON ON 8 T = 24 SS = 10 Between Within Total Source SS T = 20 SS = 10 df 2 2 T = 4 SS = 4 MS
