1. The criminal record mean was 8.0 (SD 2.12). The clean record group mean was 4.0 (SD 2.24). The no information group mean was 5.0 (SD 2.55). The overall test was statistically significant, F (2, 12) = 4.06, p =.045. The Tukey post hoc test results were significant for the criminal record group versus the clean record group ( F (1, 12) = 4.00, p = .044) and vice versa ( F (1, 12) = -4.00, p =.044). All other comparisons were not significant. Unlike the Tukey post hoc test, the Scheffe post hoc showed that the difference between the criminal record group and the clean record group, F (1, 12) = 4.00, p = .054, as well as all other comparisons were not significant. 2. In order to use planned comparisons I would need to decide what means should be

Unformatted text preview: significantly different from what other means before the study is conducted. This is useful when you have reason to expect a specific pattern of results. However, Post Hoc tests are performed after the fact. These tests are used to see which means are different from which other means. It is used to evaluate pairs of groups. If this were my study, I would have used a post hoc test, in order to evaluate and compare the means of the groups further, after the study and initial test was ran. 3. If I were going to report a post hoc test it would be the Tukey’s test. The reason for this being that it actually showed some significant results. Whereas the Scheffe’s test had no significant results, whatsoever. Exercise 2...

### What students are saying

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
