The Mozart effect refers to a boost of average performance on tests for elementary school students if the students listen to Mozart’s chamber music for a while immediately before the test. Many educators believe that such an effect is not necessarily due to Mozart’s music per se but rather a relaxation period before the test. To support this belief, an elementary school teacher experimented by dividing her third-grade class of 15 students into three groups of 55. Students in the first group were asked to give themselves a self-administered facial massage; students in the second group listened to Mozart’s chamber music for 15 minutes; students in the third group listened to Schubert’s chamber music for 15 minutes before the test. The scores of the 15 students are given below: Group 1 Group 2 Group 3 79 82 80 81 84 81 80 86 71 89 91 90 86 82 86 a) Test, using the ANOVA F-test at the 5% level of significance, whether the data provide sufficient evidence to conclude that any of the three relaxation methods does better than the other. b) Write a brief note on what you would recommend to a client.
