Chapter 12 Activity 1. What are the independent and dependent variable(s)? 4. Can normality be assumed? Regardless of the results to question 3, continue with the analysis. Week 2: Week 3: Before: Week 1: Fall 2021 Mission: One theory is that a vitamin C treatment over several weeks will cure the virus. You investigate this by measuring symptom severity (on a scale from 1 to 10) of a group of patients. The group is given a vitamin C treatment, and you measure symptom severity before treatment and at one week intervals for three weeks. Your question: Does using vitamin C affect the symptom severity of patients with the virus? Is there a change in symptom severity from before to week 1 to week 2 to week 3? 2. Calculate the mean symptom severity score for each week. 3. Perform a Shapiro-Wilk test and report the appropriate p-values for testing the assumption of normality on each of the variables. Week 2: Week 3: Independent Variable: Dependent Variable: Before: Week 1: 8. Use APA style reporting to write up your results of this analysis. 6. Report the appropriate test statistic, p-value, and degrees of freedom that answer the research question. Test Statistic: P-value: 5. Report the appropriate test statistic and p-value to test the assumption of sphericity. Test Statistic: P-value: df1 : 7. If appropriate, use post hoc tests to determine if there is a change in symptom severity over time.
