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. Do these data indicate any significant differences among the three methods? Test with α = .05. Include a source table for this ANOVA and state whether your F ratio is significant. Calculate the η2 value for this effect and Compute Tukey’s HSD to determine exactly which methods are significantly different.
