23 maj 2022 · The chi-square test of independence is used to test whether two categorical variables are related to each other. Chi-square is often written as Χ 2 and is pronounced “kai-square” (rhymes with “eye-square”). It is also called chi-squared.
21 sty 2013 · The chi-square test is used to determine if an observed frequency distribution differs from an expected theoretical distribution. It can test goodness of fit, independence of attributes, and homogeneity. The test involves calculating chi-square by taking the sum of the squares of the differences between observed and expected frequencies divided ...

30 maj 2022 · You can use a chi-square test of independence, also known as a chi-square test of association, to determine whether two categorical variables are related. If two variables are related, the probability of one variable having a certain value is dependent on the value of the other variable.
Assumptions of the chi-square test. 1. It should be obvious that the chi-square test does not rely on assumptions such as having continuous normally distributed data like most of the other tests in this book (categorical data cannot be normally distributed because they aren’t continuous).
