To bucket age values into specific groups in a data module within Cognos Analytics, follow these steps:

Open Data Module: Open the data module where the Age column is available.

Select Age Column: Locate and select the Age column from the list of data items.

Create Data Group: Use the "Create data group" feature. This allows you to define custom groupings (buckets) based on specified ranges.

Define Groups: Define the age ranges as required: 0-6, 7-12, 13-21, 22-55, and 55 and over. Save the data group.

Creating data groups directly in the data module allows you to segment the age values efficiently, making it easier to analyze and report on the data.
