When you add a column proportions or column means test to your tables, you can select the columns that you want to test. Use the options in the Column Test dialog to select the columns to test.

To display this dialog, choose Tables > Properties from the menu and click the Statistics tab. Set up your statistics, and then click Column Test.

By specifying a character string you can assign each column with a unique character ID that is used for specifying test combinations. Each character in the string is used to allocate the column ID, with a space or period used to indicate that an ID should not be allocated. A character needs to be specified for each of the columns in the table, including BASE columns. For example:

You cannot include a period or space for hidden columns.

Enter the column IDs of the table that you want to test, separate using a forward slash character, for example:

This tests all combinations of columns A, B, and C. You can specify separate groupings of columns to test by separating groups of columns with a comma, for example:

tests all combinations of columns A, C, and E, and all combinations of columns B, D, and F.

Ensure that the column IDs you specify exist in the table, and that they correspond to valid combinations of columns to test. You can check this by running the test using the same table specification but with the default column selection.

Deselect the Use grid overlap formula checkbox to use normal overlap instead of grid overlap. This can result in faster table population. However, users must understand the differences between grid and normal overlap to ensure that the correct statistical algorithm is being used.

If grid overlap is enabled, there are two options available.

Enables you to reproduce the Quantum/Quanvert formula exactly. See Statistical tests compared to Quantum and Quanvert for more information.
