ABSTRACT
In this chapter, the author briefly considers a couple of practical test problems whose solutions are rarely discussed. These solutions should help the readers review what they have learned. He encourages the readers to think further about their research questions and how they might be tested. Normally, the author would saves ourselves a lot of work by employing the Wilson interval comparison heuristic, examines the graph and extracts part-overlapping pairs to test. For demonstration purposes, he evaluates Magnus Levin’s data by comparing ‘nearest neighbours’ by frequency, reading from the top of our graph. The author explains how to compare observed frequencies where they represented two different values of the same variable and were part of the same frequency distribution.
