We develop a Bayesian procedure to test simple null hypotheses versus bilateral alternatives in contingency tables. Given independent samples of two binomial distributions and taking a mixed prior distribution, we calculate the posterior probability that the proportion of successes in the first population is the same as in the second. This posterior probability is compared with the p-value of the classical method, obtaining a reconciliation between both results, classical and Bayesian. The obtained results are generalized for r × s tables.engjournal articlehttps//doi.org/10.1081/STA-200066364http://www.informaworld.com/smpp/title~content=t713597238~db=allopen access519.22Bayesian statisticsChi-square testsContingency tablesp-valuesEstadística matemática (Matemáticas)1209 Estadística
