1. Definition: If n independent random variables ξ₁,ξ₂,...,ξn, are subject to the standard normal distribution (also known as independent distribution in the standard normal distribution), then this n the sum of squares of random variables which

The chi-square test is the deviation between the actual observed value and the theoretical inference value of the statistical sample. The deviation between the actual observation value and the theoretical inference value determines the size of the
