Ethical sensitivity of teachers towards racial intolerance. Refer to the Journal of Moral Education (March 2010) study of the effectiveness of a program to encourage teachers to embrace racial tolerance, Exercise. Recall that the level of racial tolerance was measured for each teacher before (pretest) and after (posttest) the teachers participated in an all-day workshop on cultural competence. The original sample included 238 high school teachers. The table below lists the pretest and posttest scores for a smaller sample of 10 high school teachers. These data are saved in the TOLERANCE file. The researchers conducted a paired-difference test to gauge the effectiveness of the program. Use the smaller sample to conduct the appropriate nonparametric test at α = .01 . What do you conclude?
Teacher | Pretest | Posttest |
1 2 3 4 5 6 7 8 9 10 | 53 73 70 72 77 81 73 87 61 76 | 74 80 94 78 78 84 71 88 63 83 |
