Statistics Exercise

1.The searchers analyzed the entropy they collected as though it were at what level of measurement? d.Experimental2.What was the remember post raise authorization establish for the control convocation? The involve posttest mandate fall guy was 97.12 3.Compare the close baseline and posttest depression heaps of the observational group. Was this an expected determination? lead a rationale for your answer. The mean baseline depression gull of the observational 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 is an expected finding because after the purpose of the empowerment program the experimental groups depression showed improvement. 4.Compare the mean baseline and posttest depression scores of the control group. Do these scores intone or weaken the validity of the research results? Provide a rationale for your answer. The mean baseline depression score of the control group is 10.40 The mean posttest depression score of the control group is 10.40. The scores show no change in the control groups score. It does show a change in the empowerments score which shows a decrease in the depression scores for the experimental group.5. Which groups test scores had the least amount of variability or strewing? Provide a rationale for your answer. The control groups test scores 10.40 two at baseline and posttest showed the least amount of variability or scatter.6.Did the empowerment variable or egotism- interest self-efficacy variable demonstrate the greatest amount of dispersion? Provide a rationale for your answer. I think the self care efficacy group showed the greatest amount of dispersion. The summarize groups post test score is 1.78 lower than the baseline score. The empowerment variable total groups posttest is precisely .11 lower than the baseline group. 7.The mean ( ) is a measure of central object of a distribution while the SD is a measure o f dispersion of its scores. both and SD are descriptive statistics.8. What was the mean severity for nephritic illness 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 score was 2.97. The severity scores did not vary a lot between the control and the experimental groups. This is important as the groups were no differences in clinical and demographic characteristics.9. Which variable was least affected by the empowerment program? Provide a rationale for your answer. The mean depression score showed the least amount of change when compared to their baseline values. Only 0.66 points for depression compared to 6.44 points for self care/self efficacy and 6. 64 for empowerment. The mean score for the depression master was lower than for the empowerment and self-care self-efficacy scales.10.Was it important for the researchers to include the total means and SDs for the battlefield variables in Table 2 to promote the readers understanding of the teach results? Provide a rationale for your answer. No, it is not necessary for the reader to have the total means and the SDs for the study variables in the table to understand the study results. One can understand the results showing only the total means.
