WebYates' continuity correction can be used alongside chi-square. It makes the approximation more conservative but is not commonly used. Yates is sometimes appropriate to keep from overestimating the relationship. For large samples its effect is negligible. Then select either a one-tailed or two-tailed test. WebBut the chi-square test is only an approximation. The Yates' continuity correction is designed to make the chi-square approximation better, but it overcorrects so gives a P value that is too large (too 'conservative'). With large sample sizes, the Yates' correction makes little difference, and the chi-square test works very well. With small ...
