1. Consider the following research questions/study scenarios. For each study, discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be most appropriate for addressing the research questions? Be sure to provide a justification of the statistical method. Provide the appropriate regression model and statistical test when appropriate. a. A study was performed to determine the differences in pain experienced by children with sickle cell disease (SCD) in inpatient and outpatient settings. Pain intensity (visual analog scale) was the primary outcome of interest, but potential confounders include age and physical activity. b. Elderly subjects are participating in a trial to investigate the benefits of strength training. One of the outcomes is to investigate the expression levels of inflammatory biomarkers, a continuous variable. 15 there a relationship between post- training expression levels and the intensity of the training (a continuous variable)? .0 c. A workplace wellness program was instituted to improve employee health outcomes as related to obesity and cardiovascular health. Blood lipid levels were measured on employees prior to the implementation of the wellness program and five years later. Changes in blood lipid levels were the outcome of interest. Participants in the program were offered weekly health education meetings and time off for exercise. Data on the number of health education meetings attended, weight loss, and waist circumference were collected prior to and five years after the implementation of the wellness program. Is compliance with the program (measured by the number of meetings attended), weight loss, and changes in waist circumference related to changes in triglycerides? d. Exposure to arsenic in drinking water during pregnancy may have an impact on infant outcomes. Infants born to mothers residing in two cities, one with arsenic concentrations in the drinking water and one without, are compared to investigate whether arsenic exposure is associated with smaller head circumferences. However, the two cities are different with respect to income, prenatal care, parity, and iron supplementation
