Connect Four is played on a vertical grid that consists of 7 columns. Players take turns dropping their colored discs into one of these columns, aiming to connect four of their own discs in a row—either horizontally, vertically, or diagonally.
There are seven columns and six rows.
The degrees of freedom for any contingency table can be calculated simply by the formula (r-1)x(c-1) where r= the number of rows and c= the number of columns. Thus for a contingency table with four rows and four columns the degrees of freedom are 3x3 = 9.
