25.) 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. For this problem, use α = 0.05 to find whether there are significant differences among the three methods. Then, compute Tukey's HSD to determine exactly which methods are significantly different. You may use SPSS for this problem. Quizzes 5 Exams 3 Final Only 0 7 6 2 4 7 0 G = 48 EX2=272 8 4 2 T=24 SS=10 T=20 T=4 SS=10 SS=4 Hint: You should draw your table (see problem 24 for example) and fill in all values. Then, calculate effect size (n²). Finally, use Tukey's HSD to determine which differences are statistically significant. Make sure to answer all parts of this question.
