Question

Quizplus · Accepted Answer

Hypothesis-testing procedures based on ranks are nonparametric tests because they do not assume a specific distribution of the population being sampled. They are also called distribution-free tests because they do not rely on assumptions regarding the distribution of the data. Therefore, the correct answer is both A (nonparametric tests) and C (distribution-free tests).
