□ EXERCISE 16 Questions to be Graded 1. The researchers analyzed the data they collected as though it were at what level of measurement?
a. Nominal b. Ordinal c. Interval/ratio d. Experimental 2. What was the mean posttest empowerment score for the control group? 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 for depression 14.00 and the post-test for depression was 13.36. The post-test score is 0.64 lower than the baseline score which is what the study hypothesized. The study results state “This study found that there were significant differences in improvement of empowerment, self-care self-efficacy, and depression in patients who were in the intervention group using empowerment strategies than with the control group patients” (Grove, 2007).
4. Compare the mean baseline and posttest depression scores of the control group. Do these scores strengthen or weaken the validity of the research results? Provide a rationale for your answer.
The mean baseline and post-test depression score was 10.40. These scores strengthen the validity of the research results because it shows that depression did not improve for the patients within the control group but the scores did change for the patients in the experimental group. 5. Which group 's test scores had the least amount of variability or dispersion? Provide a rationale for your answer. The control group had the least amount of variability with the depression score which stayed with a SD of 10.4.
6. Did the empowerment variable or self-care self-efficacy variable demonstrate the greatest amount of dispersion? Provide a rationale for your answer.
The empowerment variable demonstrated the greatest amount
