1. Problems

The problems are from Fenton & Bieman, Chapter 2, pp 80-82.

  1. (10 points) Problem #5 page 80: For the empirical and numerical relation system of Example 2.5 (also see the empirical relations in Figure 2.1), determine which of the following numerical assignments satisfy the representation condition:

    1. M(Wonderman) = 100; M(Frankie) = 90; M(Peter) = 60
    2. M(Wonderman) = 100; M(Frankie) = 120; M(Peter) = 60
    3. M(Wonderman) = 100; M(Frankie) = 120; M(Peter) = 50
    4. M(Wonderman) = 68; M(Frankie) = 75; M(Peter) = 40

  2. (10 points) Problem #10, page 81: Explain why neither M4 nor M5 is a valid mapping in Example 2.16.

  3. (10 points) Problem #16, page 82: Show that, for nominal scale measures, the median is not a meaningful notion of average, but the mode (that is, the most commonly occurring class of item) is meaningful.
