WebApr 13, 2024 · The use of a chi-square table that we will examine is to determine a critical value. Critical values are important in both hypothesis tests and confidence intervals. For hypothesis tests, a critical value tells us the boundary of how extreme a test statistic we need to reject the null hypothesis. 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.
