同学你好,对于这道题,非参数检验的特点是,第一点,假设中是不包含具体参数的,比如说让你检验一个变量是否服从正态分布。而参数检验的假设中会涉及具体参数,比如均值、方差、标准差是否等于或者大于小于某个值等等;第二点,非参数检验可以检验一组数据的排序状况,或者正负号。所以B和C选项描述的都是非参数检验的特点。

关于非参数检验的更多的知识点可以再去听一下R12最后一个视频,何老师是有讲到这个概念的。

NO.PZ2018062016000146 问题如下 Whiof the following statements on a non-parametric test is least accurate? A.It makes maximassumptions about the population. B.The sample ta cgiven in ranks. C.The hypothesis esn't concern a parameter. A is correct. A non-parametric test is a test this not concernewith a parameter, or a test thmakes minimassumptions about the population from whithe sample comes. There are three situations in this proceres: when the ta we use not meet stributionassumptions, when the ta are given in ranks, or when the hypothesis we are aressing es not concern a parameter. c为什么不正确呀,不涉及参数不是应该就使用非参数检验吗?

There are three situations in this proceres: when the ta we use not meet stributionassumptions, when the ta are given in ranks, or when the hypothesis we are aressing es not concern a parameter.以及non的情况不是1.要么不是参数 2.要么是参数但不符合条件,所以c我觉得也是错的,感觉只说了一半。

请问,假设检验是不是分参数检验和非参数检验?
