问题如下：

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.

老师，我想问下这个是什么知识点，不太清楚这个是在考什么

同学你好，

这道题考察的是non-parametric test的性质，可以参考讲义中的这个地方。

请问，假设检验是不是分参数检验和非参数检验？
