Tables of the Wilcoxon signed rank statistic T are sometimes inaccurate. This article presents a way to generate accurate tables that are much more extensive than have been produced to date. The method is also used to provide a measure of significance for experimental values of T that are table independent. A method of approximating the Wilcoxon statistic by a normal distribution is briefly assessed.
