A statistical measure of goodness of fit, independence, or homogeneity. The Chi-square test can be used to determine whether a sample of data was drawn from a normally distributed population by comparing the sample's frequency distribution with the normal distribution. It can also be used to determine whether two variables are independent by comparing their observed joint occurrence with their expected joint occurrence, assuming independence. Finally, it can be used to determine whether or not categories of a single variable are represented in the same proportions in two or more populations.
