Introduction to Two-Way Tables

What you’ll learn to do: Analyze the relationship between two categorical variables using a two-way table.

Recall, categorical data is data that consists of labels (such as person’s gender, an object’s color, or location). Since categorical data does not return a measurement, it is often convenient to summarize study results with counts (for example, total number of females, or total number of males). In this section, we introduce two way tables and conditional percentages as a way to investigate possible relationships between two categorical variables.
