NO.PZ2018062016000144

问题如下：

Which of the following statements on chi-square test is most appropriate?

选项：

A.

It's used in tests concerning the variance of single normally distributed population.

B.

It's not sensitive to violations of its assumptions.

C.

It can use in the condition of the sample which is less random.

解释：

A is correct. The chi-squared test is used in tests concerning the variance of a single normally distributed population. It's sensitive to violations of its assumptions. If the sample is not actually random, the chi-square test are likely to be faulty.

请问T检验，卡方检验，F检验，三个都是特殊的正态分布对吗？
