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 the empowerment program the experimental group’s depression would improve.

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 posttest depression scores of the control group have no change and stays at 10.40. These scores strengthen the validity of the research results because it shows that without the empowerment program, the control group’s depression has not improved.

5. Which group's test scores had the least amount of variability or dispersion? Provide a rationale for your answer.

The control group’s test scores had the least amount of variability or dispersion. Their depression baseline (SD=10.34) and posttest (SD=10.34) had no changes.

6. Did the empowerment variable or self-care self-efficacy variable demonstrate the greatest amount of dispersion? Provide a rationale for your answer.

The self-care self-efficacy variable demonstrated the greatest amount of dispersion. The total group’s posttest score is 1.78 lower than the baseline score. Whereas the empowerment variable total group’s posttest score is only 0.11 lower than the baseline...

1. The null hypothesis would be: There is no difference in levels of empowerment, self-care and efficacy, or depression in patients with end stage renal disease that have attended an empowerment program.
2. The average baseline depression score in the experimental group was 14.00. This value is pulled from the Mean Column
3. The baseline number for the self-care and efficacy patients was 89.56, where...

...PEARSON’S PRODUCT-MOMENT CORRELATION COEFFICIENT
ANSWERS TO EXERCISE 23
Question 1
The r value for the relationship between Hamstring strength index 60o and the Shuttle run test is -0.149. This r value shows a weak correlation between the two variables, as it is less than the 0.3 threshold for significance. Therefore, the r value is not significant.
Question 2
Between r=1.00 and r=-1.00, there is no difference in terms of strength. Both values are on the extreme ends of the...

6. Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single group? Provide rationale for your answer.
ANOVA cannot be used to test proposed relationships or predicted correlations between variables in a single group because it is designed to test for correlations and interactions amongst groups, i.e. in the test group of patients with OA you are testing the correlations between those who do not use GI and PMR and...
