WebbChi-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. http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/fermi.html free preschool newsletter template
