When working with weighted data, it is good practice to show the unweighted base values in your tables in addition to the weighted base values. This is particularly important when showing percentages. To facilitate this, by default, UNICOM Intelligence Reporter - Survey Tabulation automatically adds an unweighted base element at the start of each variable in a weighted table. For an example of a weighted table containing unweighted base elements, see Counts and unweighted counts.

The unweighted base element shows the total number of cases in the variable before any weighting has been applied. Only one value is ever shown in the table cells formed from the unweighted base element, even when there are multiple cell contents. The value that is shown is the unweighted base count, regardless what cell contents have been requested for the table.

To stop the automatic insertion of the unweighted base elements, select Suppress unweighted base on the Preferences tab. However, you should be careful to ensure that the unweighted base element is shown when necessary, in order to comply with good practice guidelines.
