A school district is experimenting with two different methods of instruction to improve the performance of elementary school students. The first, €œtraditional€ method emphasizes learning through memorization, and the second, €œmodern€ method emphasizes learning through individual discovery. As the first cross-tabulation indicates, the two methods seem to be equally effective in their impact on student performance. Some educators, however, dispute this result; they argue that the best method depends on the intelligence of the student. To test this hypothesis, they examine the relationship between instructional method and performance in each of three groups€”students with low, medium, and high intelligence. Do the accompanying cross-tabulations support this hypothesis? Which method should the school district employ for which type of student? Explain your answer.
