How to Make a Summary Table

Briefly

Choose Summary Table from the Insert menu. Then drag attributes to the top or side of the table. If you want to compute different quantities, choose Add Formula from the Summary menu.

A summary table gives you summary information about a collection, for example, the mean and median of a numeric attribute or counts for the various categories in a categorical attribute. (About continuous and categorical attributes)

To make a summary table work, first you have to make one, then you have to tell it what to summarize.

1. To make a new, empty summary table, choose Summary Table from the Insert menu or drag the summary table icon off the shelf.

2. Drag an attribute name from an Inspector or from the column header in a Case Table to the top or side of the table.
