The best displays for bivariate categorical data depend on the nature of the data and the research question. Here are a few common types of displays for bivariate categorical data:
Clustered Bar Charts: This display shows the frequency of each category of two variables side-by-side.
Stacked Bar Charts: This display shows the frequency of each category of two variables stacked on top of each other.
Mosaic Plots: This display shows the relative proportion of each combination of two categorical variables by area.
Heat Maps: This display is a two-dimensional table that is color-coded to show the relationship between two categorical variables.
Tree Maps: This display shows the proportion of each category of two variables by area.
The choice of display should be guided by the nature of the data and the research question being addressed.
