The default grouping procedure simply partitions a column based on its distinct values. For example, if a column contains state abbreviations CA, NY, and WA, then the default grouping produces one group for CA, one group for NY, and one group for WA.
If this default grouping is not satisfactory, you can create a different partition with Named Grouping. A Named (User-Defined) Grouping is a reusable set of custom conditions (i.e., rules) that partition the data into the desired groups.
To create a Named Grouping, follow these steps:
1. Click the 'New Object' button in the toolbar, and select 'Grouping'. This opens the 'Grouping' dialog box.
2. In the 'Name' field, enter a name for the grouping assembly. This is the title of the grouping object in the Worksheet. (After the grouping object is created, you can edit the grouping name from the text field at the top of the Worksheet.)
