Mosaic displays is the graphical display of the standardized residuals from the fitting a log-linear model to a contingency table in which the colour and outline of the mosaic's 'tiles' are used to indicate size and the direction of the residuals with area of the 'tiles' being proportional to corresponding number of cases.
