Yates correction for small sample size is used to adjust for the potential bias in chi-square tests when the sample size is small. It involves reducing the value of the difference between observed and expected frequencies in each cell by 0.5 before squaring and summing them up. This correction accounts for the fact that the chi-square distribution is discrete and tends to overestimate the significance of the test statistic with small sample sizes.
