2023 1 What demographic variables were measured at the nominal level of measurement in the Oh et al 2014 study Provide

  

1.  What demographic variables were measured at the nominal level of measurement in the Oh et al. (2014) study? Provide a rationale for your answer.

2.   What statistics were calculated to describe body mass index (BMI) in  this study? Were these appropriate? Provide a rationale for your answer.

3.   Were the distributions of scores for BMI similar for the intervention  and control groups? Provide a rationale for your answer.

4.  Was there a significant difference in BMI between the intervention and control groups? Provide a rationale for your answer.

5.   Based on the sample size of N = 41, what frequency and percentage of  the sample smoked? What frequency and percentage of the sample were  non-drinkers (alcohol)? Show your calculations and round to the nearest  whole percent.

6.  What measurement method was used to measure the  bone mineral density (BMD) for the study participants? Discuss the  quality of this measurement method and document your response.

7.   What statistic was calculated to determine differences between the  intervention and control groups for the lumbar and femur neck BMDs? Were  the groups significantly different for BMDs?

8.  The researchers  stated that there were no significant differences in the baseline  characteristics of the intervention and control groups (see Table 2).  Are these groups heterogeneous or homogeneous at the beginning of the  study? Why is this important in testing the effectiveness of the  therapeutic lifestyle modification (TLM) program?

9.  Oh et al. (2014,  p. 296) stated that “the adherence rate to the TLM program was 99.6%.”  Discuss the importance of intervention adherence, and document your  response.

10.  Was the sample for this study adequately described? Provide a rationale for your answer.
