Which of the following statements on a non-parametric test is least accurate?
选项:
A.It makes maximal assumptions about the population.
B.The sample data can be given in ranks.
C.The hypothesis doesn't concern a parameter.
解释:
A is correct. A non-parametric test is a test that is not concerned with a parameter, or a test that makes minimal assumptions about the population from which the sample comes. There are three situations in this procedures: when the data we use not meet distributional assumptions, when the data are given in ranks, or when the hypothesis we are addressing does not concern a parameter.
