Yates's continuity correction deducts 0.5 from the absolute difference between the observed and expected values in each cell of a contingency table before squaring and summing them up to obtain the chi-square statistic. This is done to account for the fact that the chi-square distribution is continuous, whereas the cell counts in the table are discrete.
