Show that X2 = n∑∑(pij – pi+ p+j)2/pi+ p+j. Thus, X2

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.
