This article describes how to go from a standard crosstab or grid table...
...to a table that displays an Average of all the rows per column:
Method
- Select your table.
- In the toolbar, go to Automate > Browse Online Library > Table Computations > Add Average of Each Column.
- Select the Statistic to use (if different from the default).
- Set the Position to place the new column on the top or bottom.
- Press OK.
This rule adds an extra row to the bottom of the table, which shows the Average of the statistics that are shown in the columns. Rows that are duplicates of other rows, for example, the NET row, are not included in the computation of the average. Note, this rule can only apply to a single statistic, and no significance tests are conducted on these averages.
Note, if you select Switch rows and columns on your table, the rule will no longer work due to the table dimensions changing. In this case, you will have to apply the Add Average of Each Row rule instead.
Technical details
Statistical tests are not performed on these cells. Averaging is not performed on the statistics shown in Statistics - Right.
