WebThe degrees of freedom for chi square test in contingency table is determined by the number of 'expected observations' estimated independently. In your 2x3 table since row and column totals are already known, therefore you need estimate just two expected observations using formula (row total)*(column total)/N. Remaining expected … 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.
