Show that X 2 = n(p ij p i+ p +j ) 2 /p i+ p
Question:
Show that X2 = n∑∑(pij – pi+ p+j)2/pi+ p+j. Thus, X2 can be large when n is large, regardless of whether the association is practically important. Explain why this test, like other tests, simply indicates the degree of evidence against H0 and does not describe strength of association. (“Like fire, the chi-square test is an excellent servant and a bad master,” Sir Austin Bradford Hill, Proc. Roy. Soc. Med. 58:295—300, 1965.)
