Question
Read the research abstract below. Then identify: a) the independent variable b) the levels of the independent variable c) the dependent variable d) the measurement scale of the dependent variables e) whether the dependent variables are continuous or discrete. Objective: To determine how successful the 14-week B.A.L.A.N.C.E. program was in reducing risk factors of metabolic syndrome, and determine if participants viewed this program as helping build a healthy lifestyle. Design, Setting, Participants, and Intervention: Eighty-nine university employees at risk for metabolic syndrome participated in the program between 2011-2014. Participants received three individual counseling sessions with an RD, attended 10 nutrition education sessions, and had access to a personal trainer for 60 minutes/week. After the 14-week intervention, participants attended 5 monthly group meetings until the one-year mark. Participants were invited to complete a perceptions survey after completion of the program: 40 completed the survey. Outcome Measures and Analysis: BMI, abdominal girth, HDL and LDL cholesterol, and blood pressure were measured at week one, week 14 and one year follow-up. Fitness was assessed at baseline and week 14 using paired t-tests. Results: Paired t-tests showed significant reductions in BMI, girth, systolic and diastolic BP, muscular strength, and VO2 Max after 14 weeks. Conclusions and Implications: Results show a short term worksite wellness program was effective in reducing metabolic syndrome risk factors, and participants perceived the program as being beneficial to their health.Explanation / Answer
(a)
Here independent variable are the participants that participate in the program and complete the survey. That is independent variable is 40 participnats who complete the survey.
(b)
The independent variable is categorical variable. Level is nominal.
(c)
The dependent variable is risk factors of metabolic syndrome like BMI, strength, girth, systolic, and diastolic BP, muscular strength and VO2 Max.
(d)
Level of measurements is ratio.
(e)
Since these variable can take any values, that is these variables values are uncontable so these are continuous.
