# Bivariate Data

Bivariate data is a set of data that has been collected in two variables. It shows a relationship between the variables. Each data value in one variable corresponds to a data value in the other variable. A data set with the shoe sizes and heights of people is an example of bivariate data.

A scatter plot is used to represent bivariate data.

This scatter plot shows that tall people tend to have larger shoe sizes. Keep in mind that different data sets may have different types of relationships.
