WebBasically, measures of association for 2 × 2 tables can be grouped in two classes: those relying on (a) (a function of) the cross-product ratio and those based on (b) the product-moment (Pearson) correlation, or a function thereof. The cross-product ratio, mostly known as the odds-ratio, is simply α = p 11 p 22 / p 12 p 21. http://changingminds.org/explanations/research/analysis/phi.htm
