The percentage points table of the Chi-Square distribution lists numbers called critical values ranging from 0.1 % to 99.9 %. The value v represents degree of freedom, i.e., the total number of free parameters being tested in a statistical comparison. This table depicts the chi square percentage points from 0.1 to 50 %.
