尽管有相反的建议，医学研究人员仍然经常使用耶茨校正的卡方统计量分析2 × 2列联表。研究表明，这些“校正”的统计量过于保守，传统的皮尔逊卡方通常可以充分控制I类错误概率。本文提出了一个直截了当的论点，反对使用耶茨的连续性校正和费舍尔的确切概率检验。
Despite recommendations to the contrary, medical researchers still routinely use the Yates‐corrected chisquare statistic in analyses of 2 × 2 contingency tables. Research has shown that these ‘corrected’ statistics are overly conservative and that the conventional Pearson chi‐square generally provides adequate control over type I error probabilities. This paper makes a straightforward argument against use of Yates's correction for continuity and Fisher's exact probability test.
