Like the other two plots, the mosaic plot is arranged so that the cells with observed values > expected values are associated with the larger rectangles. Also, the widths of the rectangles reflect the fact that the marginal value of the urethritis positive patients is larger than that of the urethritis negative patients (210 versus 95). Likewise, the heights of the rectangles reflect the fact that the marginal value of the gonorrhea positive patients is larger than that of the gonorrhea negative patients (200 versus 105).
