1. What demographic variables were measured at least at the interval level of measurement?
Interval level of measurement allow for the degree of difference between items but not the ratio. The interval levels of measurement that are included in this study sample are Age, Income, Length of labor, Return to work, and Number of hours working per week.
2. 2. What statistics were used to describe the length of labor in this study? Were these appropriate?
Descriptive statistics was utilized
Sample size (30), Mean(14.63) and Standard Deviation (7.78) were used to describe the length of labor in the experimental group and Population (33), Mean (12.79), and Standard Deviation (7.2) were used to describe length of labor in the control group. Because length of labor is considered an interval level of measurement, using these statistics were appropriate.
3. What other statistic could have been used to describe the length of labor? Provide a rationale for your answer.
Median could have been used as the mean and standard deviations for both groups were close.
Length of labor could have also included statistical data on the duration of phases of labor. Since all the mothers are primiparous mothers, the data would show if there were trends in a certain phase.
From this data you could pull the Mode from each phase of labor. Inferential statistics might be helpful s well because it would take into account randomness as well as associations
4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide a rationale for your answer.
Yes. The number of subjects were close, 30 vs 33. The SD of the experimental group was on 0.58% higher than the control group while the mean was only 1.84% higher. Neither of these differences is significant.
5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer.
Yes, they were. The experimental group had M (13)
