□ EXERCISE 16 Questions * 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
Because the mean is calculated and mean is the best measure of central tendency when the data of interval or ratio scale. * 2. What was the mean posttest empowerment score for the control group?
The mean posttest empowerment score for the control group is 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

In terms of different variable, the Empowerment group’s test scores had the least amount of variability or dispersion because the standard deviation for baseline as well as for posttest is smaller as compare to any other group’s test scores. * 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 demonstrate the greatest amount of dispersion as compare to empowerment group because the standard deviation is higher in self-care self-efficacy group. * 7. The mean (Median) is a measure of location (central tendency) of a distribution while the SD is a measure of scale (variability) of its scores. Both mean and SD are measure of descriptive statistics.

* 8. What was the mean severity for renal disease 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 is increased after the treatment in both the experimental and control group but there is only a slight increase in the mean value for control group which does not seem significant. If we look at the overall mean score of baseline and posttest we can say that the posttest mean score is increased with
