10.1: Chi-Square Distribution
A χ2-distribution (chi-square, pronounced “ki-square”) is another special type of distribution for a continuous random variable. The sampling distribution for a variance and standard deviation follows a chi-square distribution.
10.2: Goodness of Fit Test
The χ2 goodness-of-fit test can be used to test the distribution of three or more proportions within a single population.
10.3: Test for Independence
Using the chi-square test for independence to test the independence of two categorical variables. Includes worked examples.
