Using Statistics to Describe a Study Sample

1. What demographic variables were measured at least at the interval level of measurement?
Answer:
The demographic variables that are measured at the interval level are: 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?
Answer:
The statistics used to describe the length of labor in this study were mean and standard deviation. These were appropriate as they both can be calculated at the interval level of measurement. 3. What other statistic could have been used to describe the length of labor? Provide a rationale for you answer.
Answer:
The median could be used though the mean and standard deviation are closer for both of the groups.

4. Were the distributions of scores similar for the experimental and control groups for the length of labor? Provide rationale for your answer.
Answer:
Yes, the standard deviation measured the average deviation values of the mean. So, the difference between the two groups would be 0.48 hours which in this case is less than 30 minutes so the mean had a difference of 1.84 hours.

5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer.
Answer:
Yes, both of the groups were similar in their type of feeding though the difference in breast feeding was 1.1% and the difference in bottle feeding was 3.1% and the difference in bottle and breast feeding was 0.7%.

6. What was the marital status mode for the subjects in the experimental and control groups? Provide both the frequency and the control groups? Provide rationale for your answers.
Answer:
The marital status method for the experimental group that was married had a

The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619, p = 0.005. Discuss each aspect of these results. * The F-value suggests that there is a significant difference between the results of the control and treatment groups. The P-value of 0.005 is < the alpha of 0.05. This suggest that the groups are significantly different and the null hypothesis should be rejected. 2. State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients’ mobility level. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks? Provide a rationale for your answer. * Treatment group mean = control group mean * With the p-value being < the alpha, the null hypothesis would be rejected indicating the difference in the mean mobility scores. 3. The researchers stated that the participants in the intervention group reported a reduction in mobility difficulty at week 12. Was this result statistically significant, and if so at what probability? * The p-value of 0.005 suggests that the results are statistically significant. 4. If the...

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. 8. Can the findings from this study be generalized to Black women? Provide a rationale for your answer. 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? 10.
