Use this diagram to further explain the difference between marginal and conditional proportions.
The height & width of each rectangular block corresponds to a marginal and a conditional proportion. Click on any block to display these. The area of any rectangle is the joint proportion.
height * width = P(X) * P(Y given X) = P(Y) * P(X given Y)
Choose Group by Bruising to show the other marginal and conditional proportions.
