EXERCISE 11
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 control groups for the length of labor? Provide a rationale for your answer.
It is different, because the mean of the experimental group is 14.63 while the mean of the control group is 12.79standard deviation of the experimental group is 7.78 and control group is 7.2
5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer.
yes , the experimental and control groups were almost similar in their type of feeding.in the experimental group percentage of breast feeding were 40.6while in the control group it was 41.7.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
