Question description

Do piano lessons improve the spatial-temporal reasoning of preschool children? This question was examined by comparing the change scores (after treatment minus before treatment) of 34 children who took piano lessons with the scores of 44 children who did not. The latter group actually contained three groups of children: 10 were given singing lessons, 20 had some computer instruction, and 14 received no extra lessons. The data appear in Table 12.4.



Use the Bonferroni or another multiple comparisons procedure to compare the group means. Summarize the results and support your conclusions with a graph of the means.
