摘要：The Pearson’s chi-square test represents a nonparametric test more used in Biomedicine and Social Sciences, but
it introduces an error for 2x2 contingency tables, when a discrete probability distribution is approximated with a
continuous distribution. The first author to introduce the continuity correction of Pearson’s chi-square test has been
Yates F. (1934). Unfortunately, Yates’s correction may tend to overcorrect of p-value, this can implicate an overly
conservative result. Therefore many authors have introduced variants Pearson’s chi-square statistic, as alternative
continuity correction to Yates’s correction. The goal of this paper is to describe the most recent continuity corrections,
proposed for Pearson’s chi-square test.
