WebMay 20, 2024 · Revised on November 28, 2024. A chi-square (Χ2) distribution is a continuous probability distribution that is used in many hypothesis tests. The shape of a chi-square distribution is determined by the parameter k. The graph below shows examples of chi-square distributions with different values of k. WebSo you have three columns over here. And the degrees of freedom, and this is the rule of thumb, the degrees of freedom for your contingency table is going to be the number of rows minus 1 times the number of columns minus 1. In our situation, we have 2 rows and 3 columns. So it's going to be 2 minus 1 times 3 minus 1.
