Register to read the introduction… What statistics were used to describe the length of labor in this study? Were these appropriate?
The SD of the experimental group was 7.78 hours with a mean of 14.63 and was measured in 30 of 32 subjects. The SD of the control group was 7.2 hours with the mean being 12.79 hours, measured in 33 of 35 subjects. Based on the statistical methods to obtain the means, these number look right to me although 12 to 14 hours of labor for an average woman in today’s world is often long thus I would expect the median to actually be lower and wouldn’t necessarily agree that they are appropriate. Additionally, the only statistic used was hours or time in labor. Other factors can affect how long labor
In the control group, 31 are married (86.1%), 1 is separated/divorced (2.8%) and 3 are single (8.3%). The mode is married in each group as that is the value that appears most often. The frequency is 51 (out of 67 total subjects) a percentage of 82.1% for both groups together. 7. 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.
No, all 32 of the subjects have at least a high school education, with only 7 stopping at high school (in the experimental group). 11 had some college and 14 were college graduates or higher. Thus one could determine that 18 is a median of those with an education above high school level and this would be inaccurate. The same holds true for the control group which has 6 with no more than a high school level, 15 with some college and 13 college graduates or higher. The median would be an inaccurate reflection of the true numbers in this scenario. 8. Can the findings from this study be generalized to Black women? Provide a rationale for your
The severity did not vary significantly between the control and experimental groups and yes, this is important. Someone with more severe ESRD will have been dealing with the disease longer and may be experiencing complications not yet experienced by those with the earlier stages of ESRD. In the beginning, people are in denial about the severity of their disease but as their disease progresses, they have less and less control over their bodies and are more prone to depression. Thus, an empowerment program effective with that group is more reflective of benefits for all. But, using a wide variation of the degree of ESRD could provide some outliers that could eschew the results. 9. Which variable was least affected by the empowerment program? Provide a rationale for your answer.
Depression, because there was only 0.7% improvement in the experimental group, none in the control group and only a 0.32 total mean. Whereas with the empowerment and self-care self-efficacy, there were the improvements aforementioned, with a total of 3.34 mean improvement in empowerment and 2.42 mean improvement in self-care
