□ EXERCISE 16 Questions to be Graded 1. The researchers analyzed the data they collected as though it were at what level of measurement? d. Experimental 2. What was the mean posttest empowerment score for the control group? The mean posttest empowerment score for the control group was 97.12 3. Compare the mean baseline and posttest depression scores of the experimental group. Was this an expected finding? Provide a rationale for your answer. The mean baseline depression score of the experimental group is 14.00. The mean posttest depression score of the experimental group is 13.36. The posttest score is 0.64 lower than the baseline score. This was an expected finding because it was hypothesized that after the completion of…show more content…
Both and SD are descriptive statistics. 8. What was the mean severity for renal disease for the research subjects? What was the dispersion or variability of the renal disease severity scores? Did the severity scores vary significantly between the control and the experimental groups? Is this important? Provide a rationale for your answer. The mean severity for renal disease for the research subjects was 6.74. The dispersion or variability of the renal disease severity scores was 2.97. The self-care self-efficacy severity score did vary significantly with the experimental group’s mean posttest score being 6.44 points higher than its baseline mean score. This is important because this finding indicates that the empowerment intervention had a positive impact on the self-care self-efficacy of the patients. 9. Which variable was least affected by the empowerment program? Provide a rationale for your answer. The depression variable was least affected by the empowerment program. The experimental group’s average baseline score only dropped 0.64 from the posttest, and the control group’s average baseline score had no change in the posttest and stayed at 10.40. 10. Was it important for the researchers to include the total means and SDs for the study variables in Table 2 to promote the readers’ understanding of the study results? Provide a rationale for your answer. It was important for the researchers to include the total means and SDs
