So you have: E ( g i j H 0) = ∑ k = 1 j n ∙ k n ∙ ∙ And then use the good old "entropy" test statistic: T ( H 0) = n ∙ ∙ ∑ i, j g i j l o g ( g i j E ( … WebNow, a marginal distribution could be represented as counts or as percentages. So if you represent it as percentages, you would divide each of these counts by the total, which is 200. So 40 over 200, that would be 20%. 60 out of 200, that would be 30%. 70 out of 200, that would be 35%. 20 out of 200 is 10%. And 10 out of 200 is 5%.
