Exercise 11 (4 points per question) 1. What demographic variables were measured at least at the interval level of measurement?

Age, Income, Length of labor, Return to work, and Number of hours working per week. 2. What statistics were used to describe the length of labor in

Was the sample for this study adequately described? Provide a rationale for your answer.

I believe in some ways it was adequately described because they used many different variables in the study. However, because of the majority of the subjects being a specific race, it is more generalized toward that group or population. However when it comes to the description of this study by means of statistics, I believe that it was adequately described. Providing the comparisons with frequencies, median, standard deviation, population, and percentages, we were able to adequately determine the effectiveness of TMG.

Exercise 16 (4 points per question) 1. The researchers analyzed the data they collected as though it were at what level of measurement? (Change your response to blue.) a. nominal b. ordinal c. interval/ratio d. experimental 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 depression score for the experimental group is 14.00 and the post test score depression score for the experimental group is 13.36. I would expect to see a lower score for the experimental group, as it is the group that is being used to determine if the rate of depression was to decrease after
