WebThe chi-square test of independence determines whether there is a statistically significant relationship between categorical variables in a table. Just like other hypothesis tests, this test incorporates DF. To find the chi-square DF for a table with r rows and c columns, use this formula to calculate degrees of freedom: (r-1) (c-1). 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 …
