WebBut, as you can see, the table is pretty limited in that direction. For example, if you have a chi-square random variable with 5 degrees of freedom, you could only find the probabilities associated with the chi-square values of … WebThe degrees of freedom for a Chi-square grid are equal to the number of rows minus one times the number of columns minus one: that is, (R-1)*(C-1). In our simple 2x2 grid, the degrees of independence are therefore (2-1)*(2-1), or 1! Note that once you have put a number into one cell of a 2x2 grid, the totals determine the rest for you.
