This article describes how to go from a standard table...
...to a table with an additional row or rows that show the Effective Column Sample Size:
A table with multiple rows and columns.
1. Select your table.
2. Go to Properties > RULES on the object inspector.
3. To apply the rule, select the Plus (+) > Browse Online Library > Table Computations > Add Rows to Display Effective Column n > OK.
4. This rule then computes an estimate of Effective Column Sample Size for each column and displays it on the table. Where the cells in the column have different values of Column Sample Size, minimum and maximum range values are shown.
Effective Column Sample size is computed using:
Effective Column Sample Size = Column Sample Size / Sample Size * Effective Sample Size
5. OPTIONAL: If you only have a percentage-based statistic displayed in your table, you will need to turn off the % signs via Appearance > %.
Note, if you select Switch rows and columns on your table, the rule will no longer work due to the table dimensions changing.
