“Exercise 11 - Using Statistics to Describe a Study Sample” “Name:” _SM___________________________ The demographic variables at the interval level of measurement were length of labor, and number of hours working per week. “1. What demographic variables were measured at least at the interval level of measurement?” “2. What statistics were used to describe the length of labor in this study? Were these appropriate?” The statistics that were used to describe the length of labor in this study were hours. They was appropriate because, the frequency is 30 and the mean is 14.63, they are used to describe the data. “3. What other statistic could have been used to describe the length of labor? Provide a rationale for your answer.”…show more content…
Also, could be inadequate due to experimental group numbers do not add up to 32 or control group do not have total 36 and the percentages also do not add up to 100% due to missing data. “Exercise 16 – Mean and Standard Deviation” “1. The researchers analyzed the data they collected as though it were at what level of measurement? (Your choices are: Nominal, Ordinal, Interval/ratio, or Experimental)” Experimental “2. What was the mean posttest empowerment score for the control group?” 97.12 The depression groups baseline and posttest depression mean scores dropped by 0.64 (14 - 13.36). The hypothesis stated that the empowerment program will result in the improvement in the depression result by decreasing and that is why this was expected. As the depression result is improving this is appositive impact on the self-care efficiency of the ESRD patients. “3. Compare the mean baseline and posttest depression scores of the experimental group. Was this an expected finding? Provide a rationale for your answer.” There is no change in the mean baseline and posttest depression scores and it was the similar. As the depression result didn’t change as stated in the hypothesis, it is an unexpected finding. That is why the scores weaken the validity of the research result as scores neither improved nor go down. “4. Compare the mean baseline and posttest depression scores of the control group. Do these scores strengthen or weaken the validity of the
