问一道题：NO.PZ2018062016000146

  1. CFA I
  2. Quantitative

问题如下：

Which of the following statements on a non-parametric test is least accurate?

选项：

A.

It's 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.

请问，假设检验是不是分参数检验和非参数检验？

同学你好，

可以这么分，这是个大范围的分类。
