Questions to be graded for Exercise 11
1. What demographic variables were measured at least at the interval level of measurement?
Length of labor and number of hours working per week.
2. What statistics were used to describe the length of labor in this study? Were these appropriate?
The length of labor was described with the experimental and control groups using means and standard deviations. There could be some misleading data if a couple of subjects worked a lot more hours than the rest.
3. What other statistic could have been used to describe the length of labor? Provide a rationale for your answer.

1%. Control group: Frequency 31 and 86.1%.
7. Could a median be determined for the education data? If so, what would the median be for education for the experimental and the control groups? Provide a rationale for your answer.
Yes the median can be determined. The median for the experimental group is some college and for the control group is college graduate or higher. The reason for this is that the percentage of people fall in middle of the group of numbers.
8. Can the findings from this study be generalized to Black women? Provide a rationale for your answer.
No, the study findings cannot be generalized to Black women. The experimental group only had one Black woman in the experimental group and the control group had no Black women. .
9. If there were 32 subjects in the experimental group and 36 subjects in the control group, why is the income data only reported for 30 subjects in the experimental group and 34 subjects in the control group?
The “Note” at the bottom of Table 1, Numbers do not always total 32 for the experimental group or 36 for control group because of missing data.
10. Was the sample for this study adequately described? Provide a rationale for your answer.
Yes, the sample for this study was adequately described that the used first time mothers, how they were selected and placed in either the experimental or control groups. The researchers also stated that it was a quasi-experimental study which is sued to estimate the causal impact of an intervention on its target population.
Questions to be graded for Exercise 16
1. The researchers analyzed the data they collected as though it were at what level of measurement? C. Interval/ratio
2. What was the mean posttest empowerment score for the control group?
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 experimental group subjects scored lower on the depression posttest then the baseline, meaning that they were less depressed after the completion of the empowerment program. Yes this was an expected finding, because the researchers hypothesized that the empowerment program would be beneficial the patient and result in a decrease in their depression scores.
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 for the control...
