To calculate the degrees of freedom for a chi-square test, first create a contingency table and then determine the number of rows and columns that are in the chi-square test. Take the number of rows minus one and multiply that number by the number of columns minus one. The resulting figure is the degrees of freedom for the chi-square test.
