WebChi-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: the χ 2 value (23.57) and; the degrees of freedom (df). The degrees of freedom is basically a number that determines the exact shape of our distribution. The figure below illustrates this point. Right. Use the table below to find the chi-square critical value for your chi-square test or confidence interval or download the chi-square distribution table (PDF).
