WebChi-Square Table. This chi-square table provides the critical values for chi-square (χ 2) hypothesis tests. The column and row intersections are the right-tail critical values for a given probability and degrees of freedom. Typically, use your significance level to choose the column. Rows contain the degrees of freedom for your chi-square test. WebMar 23, 2024 · In order to use the table, one must determine the stringency of the test. The lower the p-value, the more stringent the statistics. Degrees of Freedom (DF) are also calculated to determine which value on the table to use. Degrees of Freedom is the number of classes or categories there are in the observations minus 1. DF=n-1
