Question

2-1 Your orgnization collects data on individual patients shown in Appendix Table 2. Identify wheather each variable is measured nominally, oedinally, or as an interval/ratio variable.

Table 2

Table 2-3

Correlation Coeficient

r = .997

Critical Value of r = .532 with n =14

2-2 What statistical measures would you use to summarize the variable 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 ypu run to test this hypothesis?

2-4 Perform the test defined in Table 2-3. State your conculsions.

2-5 Compare gender and having Rx coverage. State your hypothesis. Perform the approppriate statistical test and interpret.

Explanation / Answer

Answer to 2.1

The description of the variables is as follows

Age is ratio scale

The satistfaction level is ordinal , since it cannot be measured by still it is expressed in ranking order

Insurer data is of nomial type

Same day appointment & RX are both binary format data, they are considered to be nominal only

Co. Pay is interval scale data
