Column Test
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 box to select the columns to test.
To display this dialog box, choose Tables > Properties from the menu and click the Statistics tab. Set up your statistics, and then click Column Test.
Fields on the Column Test dialog box
Column IDs
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:
"....MF.NG"
You cannot include a period or space for hidden columns.
Test Columns
Enter the column IDs of the table that you want to test, separate using a forward slash character, for example:
"A/B/C"
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:
"A/C/E, B/D/F"
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.
Grid detection method
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.
▪Classify as a grid when the variables on the side and top are multiple-response - this is the default option.
▪Classify as a grid when the variables on the tables are defined as grids in the metadata - this is the grid detection method used in Data Collection 5.6 or earlier.
Use the Quantum/Quanvert column test formula
Enables you to reproduce the Quantum/Quanvert formula exactly. See
