HSCI 432


For this case study assignment, you will work in groups of one to three people to:


  1. Examine and explore the “data.xlsx” file and the associated data dictionary (“Data Dictionar.xlsx).
  2. Come up with a research question and hypothesis that you would like to test using this data.
  3. Test your hypothesis using “R”



  • Your analysis should include descriptive statistics for all variables included in your analysis, bivariate tests between all explanatory variables and the outcome of interest, and a multivariable model that tests your primary research question while also controlling for confounders.
    • Note: You might be conducting an “explanatory model” rather than a confounding model. Explanatory models are usually used to understand the variables associated with a single outcome rather than test whether a specific variable is associated with the outcome.
    • Your R code should be extremely well documented (i.e., lots of comments to explain what each line and section are for)
    • Your variables should be appropriately recoded.
    • Your code should be free from error.
    • Your results should be properly interpreted.
      • Note: Make sure that you look up how to interpret the results from your analysis.
