1. What demographic variables were measured at least at the interval level of measurement?

Age (yrs), Income (annual)($), Length of labor (hrs), Return to work (wks), and Number of hours working per week were measured at least at the interval level of measurement

2. What statistics were used to describe the length of labor in this study? Were these appropriate?

The variable length of labor were used to describe by ratio data that can be described by using mean, range, and standard deviation. it is also called as interval/ratio level data

3. What other statistic could have been used to describe the length of labor? Provide a rationale for your Answer.

Nominal level data could be used to describe the length of labor. This would have done by using frequencies, percentages, and mode instead of using mean, range, and standard deviation

4. Were the distributions of scores similar for the experimental and ...view middle of the document...

7.not much difference in both groups

In the experimental group percentage of bottle feeding were 53.1, while in the control group it was 50.0. There was not much difference in both groups. In the experimental group percentage of both breast and bottle feeding were 6.3while in the control group it was 5.6.not much significant difference in both groups

6. What was the marital status mode for the subjects in the experimental and control groups? Provide both The frequency and percentage for the marital status mode for both groups.

Being married was the mode for the experimental group which is78.1% and the control group which 86.1 % since most people were married in both groups. In the control group 8% more were married .percentage of married in experimental group was 78.1 and frequency was 25 and control group were 86.1 and frequency was 31.

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, a median be determined for the education data. Median for education for the experimental group is 34.4. Median for education for the control groups is 36.2

8. Can the findings from this study be generalized to Black women? Provide a rationale for your answer.

No, the findings from this study cannot be generalized to Black women. the percentage of whites were higher in both experimental and control groups were higher which is 92%in experimental and 96.55 % in control groups while the in the experimental group there were only 4% of black and in control group there were none.

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?

This is because of the missing data’s.

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

The sample for this study adequately described. Because in this the researchers presented the characteristics of their sample in a table format for the experimental and control groups. There were subgroups under race, marital status, education, type of feeding, and amount of household infant care responsibilities.
