WebThe Chi-square test, named for the Greek symbol "Chi," is used to test for differences in proportions between two or more groups. You may also see the Chi-square test called a "goodness of fit" test. That is to say, the Chi- square test is used to see if grouped data "fit" into declared groups, or if the data instead do not "fit" into the group.
