The Wilcoxon signed-rank test is the nonparametric equivalent of the one-sample t test for paired data. It is used when the data are not normally distributed or when the assumptions of the t test are not met. The test compares the difference between each pair of observations to zero and ranks them. It then calculates a test statistic based on the sum of the positive or negative ranks.
