WebOct 9, 2012 · 1 Answer. It depends on the choice of options (exact vs a normal approximation, with or without continuity correction): By default (if ‘exact’ is not specified), an exact p-value is computed if the samples contain less than 50 finite values and there are no ties. Otherwise, a normal approximation is used. wilcox.test (x, y) Wilcoxon rank ... WebR's chi square test of proportions (prop.test) uses the Yates continuity correction by default.

WebA continuity correction is the adjustment made when a continuous distribution approximates the discrete distribution. It is mostly used when a normal distribution approximates the binomial distribution. As per the central limit theorem, if the size of a sample is large enough, the sample mean of the distribution becomes roughly normal.
