7.6 Creating Crosstabulations

When you have counts for one variable, they are called one-way frequencies. When you create counts by crossing two or more variables, they are called two-way, three-way, and so on, up to n-way frequencies, or simply crosstabulations. To produce crosstabulations, use the Table Analysis task.

As in the previous section, this example uses the Volcanoes data set, but, instead of having one table for Activity and one for Type, it produces a single table showing Activity crossed with Type. Open the task by clicking the data icon in the Project Tree or Process Flow and select Tasks Describe Table Analysis from the menu bar. The Table Analysis window will open, displaying the Data page.
