2 × 2 Tables: a note on Campbell's recommendation

For 2 × 2 tables, Egon Pearson's N − 1 chi‐squared statistic is theoretically more sound than Karl Pearson's chi‐squared statistic, and provides more accurate p values. Moreover, Egon Pearson's N − 1 chi‐squared statistic is equal to the Mantel‐Haenszel chi‐squared statistic for a sin...

More Information
Summary:For 2 × 2 tables, Egon Pearson's N − 1 chi‐squared statistic is theoretically more sound than Karl Pearson's chi‐squared statistic, and provides more accurate p values. Moreover, Egon Pearson's N − 1 chi‐squared statistic is equal to the Mantel‐Haenszel chi‐squared statistic for a single 2 × 2 table, and as such, is often available in statistical software packages like SPSS, SAS, Stata, or R, which facilitates compliance with Ian Campbell's recommendations.
