Question

Quizplus · Accepted Answer

Yates's continuity correction is used to reduce the probability of Type I error in testing categorical data using a chi-squared test. It is used when the sample size is small or when the expected frequencies are low, which can make the chi-squared test overly conservative. The continuity correction adjusts the chi-squared statistic by adding or subtracting 0.5 from each cell in a 2x2 contingency table, which can result in a more accurate p-value and reduce the chance of false positives (Type I error).
