http://www.vassarstats.net/csfit.html 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.

How many variables are present in your cross-classification will determine the degrees of freedom of your χ 2 -test. In your case, your are actually cross-classifying two variables (period and country) in a 2-by-3 table. So the dof are ( 2 − 1) × ( 3 − 1) = 2 (see e.g., Pearson's chi-square test for justification of its computation).
WebThe degrees of freedom in this case is ( r − 1) ( c − 1) where r is the number of rows (number of different genes) and c is the number of columns (number of lists). The rule of thumb is that a chi squared ( χ 2) test is reasonable if all the expected values are greater than 5. Another rule of thumb says all the expected values need to be ...
