Dec 30, 2020 · How to Visualize Dichotomous Variables. We typically visualize dichotomous variables by using a simple bar chart to represent the frequencies of each value it can take on. For example, the following bar chart shows the frequencies of each gender in the previous dataset: We could also display the frequencies as percentages on the y-axis:
- Gender. In traditional demographic surveys, gender is often considered a dichotomous variable, with the categories of Male and Female.
- Alive or Dead. In biological or medical research, the central variable can be whether a subject is alive or dead.
