Exercise 11: Using Statistics to Describe a Study sample.
1. What demographic variables were measured at the interval level of measurements?
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?
Mean and standard deviation were used to describe the length of labor. These were appropriate since mean and standard deviation can be calculated on an interval level of measurement. 3. What other statistics could have been used to describe the length of labor? Provide a rationale for your answer? Range could also be used to describe the length of labor since this statistic can be used on interval data with no natural zero point.
4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide a rationale for your answer.
The distribution of scores was similar for the experimental and control groups for length of labor. The experimental group had a mean of 14.63 hours and the control group had a mean of 12.79 hours which is a difference of less than 2 hours with a SD of 7.78 for experimental and 7.2 for control.
5. Were the experimental and the control groups similar in their type of feeding? Provide a rationale for your answer.
The experimental and control groups were similar in the type of feeding. More people fed with a bottle than breast or breast and bottle in the experimental and control group. The percentages in both were lowest for breast and bottle with 6.3% for experimental and 5.6% for control. 6. What was the marital status mode for the subjects in the experimental and control groups? Provide both frequency and percentage for the marital status mode for both groups. Married was the marital status mode for the experimental group and control group since it was the largest group. The frequency and percentage are 25 and 78.1% for the
