问一道题：NO.PZ2018062016000146 [ CFA I ]

  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.

老师 选项A怎么理解呢

同学你好，

题干问非参数检验哪一项描述不正确。上课讲过结论，非参数检验不需要对总体做很多的假设。所以A选项错误。

请问，假设检验是不是分参数检验和非参数检验？
