Final Project 4 The final question involved the difference in scores on the Interpretation Anxiety subscale based on the respondents’ reported number of online courses completed. Use SPSS to conduct the analysis that is appropriate for this research question and answer each of the questions. If a statistical significance test is used, you should use .05 as the critical level of significance. Round descriptive statistics to two decimal places and do not round the test statistic or p-value. Questions: 1. Based on the scenario, what is the appropriate analysis for examining differences among the Interpretation Anxiety subscale scores based on the number of online courses completed? Oneway Anova Analysis and Post Hoc Tests 2. Write an appropriate null hypothesis for this analysis. There will be no statistically significant difference among the Interpretation Anxiety subscale with respect to the number of online courses completed. 3. Write an appropriate directional research hypothesis for this analysis. There will be a difference among the Interpretation Anxiety subscale with respect to the number of online courses completed. 4. What is the mean Interpretation Anxiety score for each number of online courses completed? 0-2 Courses- M= 2.79 3-7 Courses- M= 3.17 8 or more courses- M= 3.16 Total- M= 3.04 5. What is the standard deviation for each number of online courses completed? 0-2 Courses- SD= .96 3-7 Courses- SD= .80 8 or more courses- SD= .79 Total- SD= .86 6. What is the observed or computed value of the test statistic comparing the Interpretation Anxiety subscale scores based on the number of online courses completed?

F= 2.50 7. What are the reported degrees of freedom for the Between Groups variance? df= 2 8. What are the reported degrees of freedom for the Within Groups variance? df= 117 9. What is the reported level of significance? p= .086 10. Based on the results of the Scheffe post hoc test, which groups are significantly different? None of the groups are significantly different. All of them are greater than .05. 11. Present the results as they might appear in an article. This must include a table that reports the results of the analysis and narrative statement that reports and interprets the results of the analysis and Tukey post hoc test.’ As shown in Table 1, the results of the oneway ANOVA did not indicate a statistically significant difference, F(2, 40)= 2.50, p = .086, between 0-2 courses (M = 2.79, SD = .96), 3-7 courses (M = 3.17, SD = .80), and 8 or more courses (M = 3.16, SD = .79).
