f) What might have been the reason why the researchers did not treat the participation questionnaire data as continuous data (by using the subjects' total scores on the questionnaire) and conducted t-tests instead of the Mann-Whitney/Wilcoxon Rank Sum Test as they did when nurses' attitudes towards research were examined? (Hint: Look at the median scores and compare them to the range.) g) If the researcher ran a skewness analysis on the distribution of scores presented in Table 3 and found that the distribution was skewed, would the data be positively (right) skewed or negatively (left) skewed? h) According to Table 3, did the research utilization in-service program have a lasting effect on the research participation activities scores of the members of the experimental group? Provide a rationale for your answer. i) Could researchers use the Mann-Whitney/Wilcoxon Rank Sum test to compare the performance of the experimental group between the pretest and the posttest? Provide a rationale for your answer. 2 - Body Comp of Child- Mom Obese Using the paper linked on D2L under the heading "Body Comp of Child Mom Obese" answer the following questions: a) What was the median value for Body mass index: Total group for children of nonobese mothers? What was the median value for Body mass index: Total group for children of obese mothers? Are these results expected? b) What was the Wilcoxon matched-pairs signed-ranks test p-value for Abdominal fat (96): Total group? Was the value statistically significant, and if so, at what level? c) Which variable had a greater statistically significant, Abdominal fat (9%): Total group or Fat-free mass (kg): Total group? Provide a rationale for your answer. d) Why did the authors choose to use a Wilcoxon matched-pairs signed-ranks test? Why are the variables of age and weight lacking a Wilcoxon test value? e) Was there a control group in this study? What type of study is this? Provide a rationale for your answer. f) In your own opinion, were the results for Abdominal fat (96), Fat-free mass (kg), Body fat (90), and Body mass index of this study what you expected? g) All the participants in this study were Caucasian. How does this characteristic affect the ability to generalize the results to other populations? Provide a rationale for your
