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 this study? Were these appropriate?
Sample size, Median and Standard Deviation were used to describe the length of labor in the experimental group and Population, Median, and Standard Deviation 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.
I believe mean could have been used to describe length of labor. By calculating the mean, you can figure out the average length of labor of the population.
4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide a rationale for your answer.
No, they were not. I believe they were different because of the use of sample size for the experimental group and the use of population for the control groups.
5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer.
Yes, they were. 53.1% of the experimental group stated they prefer bottle feeding and 50% of the control group stated they prefer bottle feeding also, compared to the lower percentages of the both groups
