6.6 Summary

In this chapter, you were introduced to the concept of a contingency table with fixed marginals, and shown you could test against a wide variety of general and specific alternatives by examining the resampling distribution of the appropriate test statistic. Among the test statistics you considered were Fisher’s Exact, Freedman-Halton, Pearson’s Chi-Square, Tau, Q, Pitman’s correlation, and linear-by-linear association. These latter two statistics are to be used when you can take advantage of an ordering among the categories.
