Wilcoxon signed-ranks test

a nonparametric statistical procedure used to determine whether a single sample is derived from a population in which the median equals a specified value. The data are values obtained using a ratio scale, each is subtracted from the hypothesized value of the population median, and the difference scores are then ranked. The test takes into account the direction of the differences and gives more weight to large differences than to small differences. The symbol for the test statistic is T. Also called Wilcoxon T test. [Frank Wilcoxon]
