Quizplus · Accepted Answer

The Mann-Whitney test and the sign test are both non-parametric tests used for different purposes: the Mann-Whitney test compares the distributions of two independent samples, while the sign test is used for comparing the median of a single sample against a hypothetical median or comparing the medians of two paired samples. They are not equivalent tests.
