WebChi-square test calculation details Chi-square tests compare the observed (O) and expected (E) frequencies of the subjects. With contingency table tests, the expected frequencies are calculated in the background based on the multiplication rule of probability.

The table tells us that the probability that a chi-square random variable with 10 degrees of freedom is less than 15.99 is 0.90. Therefore, the probability that a chi-square random variable with 10 degrees of freedom is greater than 15.99 is 1−0.90, or 0.10.
