Chapter 2: Exercises 2-1, 2-2, 2-3, 2-4, 2-5 (page 48 of the text)
2-1 Your organization collects data on individual patients shown in Appendix Table 2. Identify whether each variable is measured nominally, ordinally, or as an interval/ratio variable.
2-2 What statistical measures would you use to summarize the variable for age? What about for gender? For convenience satisfaction? How would you present these graphically?
2-3 If you are interested in whether satisfaction scoring differed by the amount the individual paid as a co-pay, how would you state this inquiry as testable hypotheses (the null and alternative)? What statistical test would you run to test this hypothesis?
2-4 Perform the test defined in Table 2-3. State your conclusions.
2-5 Compare gender and having Rx coverage. State your hypotheses. Perform the appropriate statistical test and interpret.
