Summary:
Mosaic plots can help visualize contingency tables, even those complex ones, consisting of many categorical variables. This kind of display can be very helpful in understanding simple and complex associations among categorical variables, especially for three- and more way tables. That said, applications of this display are all-too-rare. This paper aims to direct the readers’ attention to this useful graphical display. To present mosaic plots, they are applied to visualize associations among questions from a survey of knowledge of and attitude towards genetically modified organisms.
