====== 第十四章：卡方检验======

======Chapter 14: Chi Square Test======

=)**本章概览 (Guide)**：
  * 之前我们学习了参数检验，参数检验一般用于等比/等距型数据，而且要求参数要服从正态分布和方差同质性。而对命名/顺序型数据，我们需要利用非参数检验。非参数检验虽然不如参数检验敏感，但是数据无需服从正态分布。卡方检验就是最常见的非参数检验之一。\\ *Previously, we learned about parameter testing, which is generally used for proportional/isometric data and requires parameters to follow a normal distribution and homogeneity of variance. For named/sequential data, we need to use non parametric tests. Although non parametric testing is not as sensitive as parametric testing, the data does not need to follow a normal distribution. The chi square test is one of the most common non parametric tests.
