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 ... http://www2.lv.psu.edu/jxm57/irp/chisquar.html
