**Side-by-side boxplots** are a useful way to compare the distribution of data values in multiple groups at once.

This tutorial explains how to create the following side-by-side boxplots in SPSS:

Let’s jump in!

**Example: How to Create Side-by-Side Boxplots in SPSS**

Suppose we have the following dataset in SPSS that contains information about points scored by basketball players on three different teams:

Suppose that we would like to create side-by-side boxplots to visualize the distribution of points scored by players on each team.

To do so, click the **Graphs **tab, then click **Boxplot**:

In the new window that appears, click the **Simple** icon, then click **Define**:

In the new window that appears, drag **Points** to the **Variable** panel, then drag **Team** to the **Category Axis** panel:

Once you click **OK**, the following side-by-side boxplots will be created:

The x-axis displays each unique team name and the y-axis displays the points for each team.

Note that the line inside of each boxplot represents the **median** while the length of the box represents the **interquartile range**.

From viewing the boxplots we can see that team C has the highest median points per player while team A has the lowest median points per player.

We can also see that team B has the largest interquartile range, which represents the difference between the 75th percentile and 25th percentile of points scored.
