•1. The researchers analyzed the data they collected as though it were at what level of measurement? oa.Nominal
ob.Ordinal
oc.Interval/ratio
od.Experimental
•2. What was the mean post-test empowerment score for the control group? The mean post-test empowerment score for the control group is 97.12 (from Table 2). •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 baseline score mean is 14 and the post-test depression score mean is 13.36, meaning they were less depressed after completing the empowerment program. This is an expected finding because the researchers had hypothesized this decrease as a result of the program. •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 scores of the control group are both identical at 10.40. Because this is the control group, no change in depression score is expected, therefore this strengthens the validity of the research results when comparing the control group results to the experimental group results. •5. Which group's test scores had the least amount of variability or dispersion? Provide a rationale for your answer. The group with the least amount of variability is the experimental empowerment post-test group, which has the lowest standard deviation of 7.28. The lower the standard deviation, the lower the variability because they are directly related. •6. Did the empowerment variable or self-care self-efficacy variable demonstrate the greatest amount of dispersion? Provide a rationale for your answer. Because the self-care self-efficacy experimental group’s baselines score has the highest standard deviation of 14.88 when compared to the empowerment variable, it has the greater...

...Exercise 36
1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619, p = 0.005. Discuss each aspect of these results.
The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 < 0.05 hence this suggests a rejection of...

conclusion about the long-term effect of the health-promotion intervention on Exercise in this study?
Answer: t=-7.75* (3months) and t= -3.93* (6 months). At 3 months, the difference in exercise from pretest was statistically significant with t = - 7.75*, P< 0.05. At 6 months the difference in exercise from pretest was also statistically significant with t = -3.93*. The...

6. What is the smallest, significant t ratio listed in Table 2? Provide a rationale for your answer.
t = 2.03* the smallest t ratio listed in Table 2. It indicates that the cholesterol level change was statistically significant from pretest to 3 months. It is greater than the given value of p<0.05
7. Why are the larger t ratios more likely to be...
