Stacked Data Format

The quantitative data is "stacked" in one column and the groups of the categorical variable are listed in the other column.

With the datafile open in a StatCrunch worksheet:

Select Graph Boxplot.

Under Select Columns: click on the appropriate quantitative variable (this is the response variable) to move it from the gray box on the left to the white box on the right.

Use the Group by: drop-down menu to choose the appropriate categorical variable (this is the explanatory variable).

Use the Grouping options: drop-down menu to select Plot groups for each column.

In the Other Options: area, check Use fences to identify outliers. This will allow you to see the 1.5IQR Rule outliers.

In the Markers: area, check Mean to display the means with the boxplots.

Press Compute!
