解释:请问:chi-square test是上课的课件Types of H testing里的哪个assumption?
NO.PZ2017092702000144问题如下 A chi-square test is most appropriate for tests concerning:A.a single variance.B.fferences between two population means with variances assumeto equal. C.fferences between two population means with variances assumeto not equal. A is correct. A chi-square test is usefor tests concerning the varianof a single normally stributepopulation.卡方检验适用于单个正态分布总体方差的检验。 请问卡方检验的知识点在哪一个reang

NO.PZ2017092702000144 卡方检验sum of the squares of k inpennt stantarnormallt stribute 为什么不是B,假设他们的Varian相等,且是1?
chi-square不是校验两个总体的吗 a怎么理解
