The chi square test for independence allows us to test the hypothesis that the categorical variables are independent of one another. As we mentioned above the r rows and c columns in the table give us r 1 c 1 degrees of freedom. 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.
Chi square test degrees of freedom we ll get the p value we re after from the chi square distribution if we give it 2 numbers.
But it may not be immediately clear why this is the correct number of degrees of freedom. Values of the chi squared distribution. Or just use the chi square calculator. For two sided tests the test statistic is compared with values from both the table for the upper tail critical values and the table for the lower tail critical values.
