Attributes in a choice design can only be categorical.

Tip: When you have completed the Attributes outline, consider selecting Save Factors from the red triangle menu. This saves the attribute names, roles, and levels in a data table that you can later reload and reuse.

Figure 18.16 Attributes Outline

The Attributes outline contains the following columns:
