Question 2
Is a new method of teaching reading to first graders (Method B) more effective than the method now in use (Method A)? You design a matched pairs experiment to answer this question. You form 20 pairs of first graders, with two children in each pair carefully matched by IQ, socioeconomic status, and reading-readiness score. You assign at random one student from each pair to Method A. The other student in the pair is taught by Method B. At the end of the first grade, all the children take a test to determine their reading skill. Assume that the higher the score on this test, the more proficient the student is at reading. Let p stand for the proportion of all possible matched pairs of children for which the child taught by Method B has the higher score. Your hypotheses are Ho: p = 0.5 (no difference in effectiveness) Ha:p > 0.5 (Method B is more effective) 12 = 0.6. 20 The result of your experiment is that Method B gave a higher score in 12 of the 20 pairs, or p If Ho is true, the 20 pairs…
