# 3.5.1 - Scatterplot with Groups

3.5.1 - Scatterplot with GroupsA scatterplot with groups can be used to display the relationship between two quantitative variables and one categorical variable. Like the scatterplot that you learned about earlier, the quantitative variables are shown on the x- and y-axes. Now, the different levels of the categorical variable are communicated using different colored points or different shaped points.

## MinitabExpress – Scatterplots with Groups

To create a scatterplot with groups in Minitab Express:

- Open the data set:
- On a PC or Mac:
**GRAPHS > Scatterplot** - Select
*Single Y Variable >**With Groups* - Double click the variable
*Weight (pounds)*in the box on the left to insert the variable into the*Y variable*box - Double click the variable
*Height (inches)*in the box on the left to insert the variable into the*X variable*box - Double click the variable
*Biological sex*in the box on the left to insert the variable into the*Group variable*box - Click
*OK*

This should result in the following scatterplot:

Select your operating system below to see a step-by-step guide for this example.

The scatterplot above shows the relationship between height and weight while noting which individuals were female and which were male use different colored and shaped markers. We can see that overall there is a positive relationship between height and weight. We can also see that females tend to be lower on both variables and males tend to be higher on both variables.
