Adding a Statistical Test

You can apply a number of statistical tests to your tables to check the statistical significance of your results.

To add a statistical test

In the Tables pane, select the table to which you want to apply the test.

Note that most of the statistical tests are valid only for certain types of table; ensure that your tables meet the restrictions for your chosen test. See the Details and Restrictions topic for the appropriate test.

If you are applying a paired preference test or a net difference test to a table, the process is slightly different from that for other statistical tests, as you also need to add a row or column to the table to contain the results. Before carrying out the remainder of these steps, you need to carry out the steps in Adding a Paired Preference Test or a Net Difference Test.

From the menu bar, choose:

Choose the Statistics tab.

Select the statistical test that you want to apply to the table.

If required, change the significance level(s) and the minimum and small base values.

Choose OK.
