Quizplus · Accepted Answer

The Wilcoxon signed-rank test is used to compare two related (correlated) groups and test whether there is a difference between the medians of the two groups. Therefore, it is the nonparametric counterpart of the correlated groups t test, which is used for the same purpose but assumes a normal distribution of the differences between the two groups. The one-sample z test, independent groups t test, and F test are all parametric tests and are not related to the Wilcoxon signed-rank test.
