WebThere are 2 primary differences between a Pearson goodness of fit test and a Pearson test of independence: The test of independence presumes that you have 2 random variables and you want to test their independence given the sample at hand. The goodness of fit test, on the other hand, works on 1 random variable at a time.

WebThe chi-square (\(\chi^2\)) test of independence is used to test for a relationship between two categorical variables. Recall that if two categorical variables are independent, then \(P(A) = P(A \mid B)\).
