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?

EXERCISES
· 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?
