Yates's correction for small sample size is used to adjust the chi-square test when the sample size is small (less than five in one or more cells). It reduces the value of the difference between f o and f e by 0.5 before squaring to give a more accurate test statistic. This adjustment is necessary because the normal chi-square test may overestimate the significance of the association between variables due to sampling variation.
