This means taking the number of rows on your original table of frequencies (minus 1) and multiplying it by the number of columns (minus 1). I.e., = σ 1 2 / σ 2 2 where σ 1 2 is assumed to be larger sample variance, and σ 2 2 is the smaller sample variance. The second argument is the degrees of freedom
