Yates' correction of continuity is used to adjust for the continuity between categories in a 2x2 contingency table when calculating the chi-square test statistic. However, recent studies have shown that the correction can result in a reduction in statistical power with little gain in controlling Type I error. Therefore, it is suggested that Yates' correction should not be used. This means that the answer is C: statistical power is reduced with little gain over Type I error control.
