Quick Start to StatTools

Here is the result. You can read more about box plots in StatTools help, but this plot makes it clear that
females tend to make smaller salaries than males (the female box is slightly to the left), and their
salaries tend to have less variation the male salaries (the female box is narrower). Note that the red
points are called outliers.
Third, you might want to see whether there is a relationship between Age and Salary, or between Years
(of experience) and Salary. The best way to do this graphically is with scatterplots.
To create one or more scatterplots:
Select Scatterplot from the Summary Graphs dropdown list. As shown in the following dialog
box, you can select any number of variables for the X axis and any for the Y axis. Those checked
in the dialog box below are recommended for now. For these selections, you will get two
scatterplots: Salary (Y) versus Age (X), and Salary (Y) versus Years (X). You can also see the
correlations between the variables below the scatterplots by checking the circled option.
