For K = 1, the generalized CMH correlation statistic equals (2.5.1). When there truly is a trend, Section 2.5.3 noted that this test is more powerful than the X and G tests of Section 2.4. To illustrate, for Table 7.5, construct the marginal 44 table relating job satisfaction and income. Show that the Pearson test (2.4.3) has X2 11.5 with df 9 (P = .24). Show that the correlation statistic with equally-spaced scores equals 7.6 based on df = 1 (P = .006).
