CHAPTER 2: THE BASICS OF MEASUREMENT
2. Answers to the questions:
a. Nominal, ordinal, interval, ratio, and absolute are the ve-scale
types.
b. e scale type for the complexity measure is ordinal, because
there is a clear notion of order, but no meaningful notion of
“equal dierence” in complexity between, say, a trivial and sim-
ple module and a simple and moderate module. A meaningful
measure of average for any ordinal scale data is the median. e
mode is also meaningful, but the mean is not.
3. e answer is given in the following table:
