1. The researchers analyzed the data they collected as though it were at what level of measurement?
a) Nominal
b) Ordinal
(c) Interval/ratio- answer
d) Experimental
1
2. What was the mean posttest empowerment score for the control group? Mean= given (n=25),(=2428) threfore, 2428÷ 25= 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.
This was an expected finding, because the researchers hypothesized that the empowerment program would be beneficial to ESRD patients and result in a decrease in their depression scores. However, the difference in the depression baseline and posttest means for the experimental group was only 0.64, which is less than what might have been expected.
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 depression scores in the research tend to be constant both being 10.14 in the mean. These scores strengthen the research validity because they evidently shows that in the control groups whereby the empowerment program was not effected no visible change took place either in the baseline or the posttest score. They further back up the research findings showing evidence even in the standard deviation which clarifies that no change occurred in the levels of depression for the sample.
5. Which group's test scores had the least amount of variability or dispersion? Provide a rationale for your answer. The experimental group’s empowerment posttest scores had the smallest amount of dispersion or variability, as indicated by the smallest SD of 7.28.
6. Did the empowerment variable or self-care self-efficacy variable demonstrate the greatest amount of dispersion? Provide a rationale for your answer. The experimental group’s
