Analyzing one categorical variable

Let's learn how to create and read bar graphs to describe categorical data.

Two-way tables

We use two-way tables to see the relationship between two categorical variables. Let's learn the basics of how to create and read two-way tables.

Distributions in two-way tables

To see see if there is a relationship between the variables in a two-way table, we look at special distributions within the two-way table. Identifying and reading marginal and conditional distributions help us to see the relationships in two-way tables.
