An attribute is a feature of a product.
A profile is a specification of product attributes.
A choice set is a collection of profiles.
A survey is a collection of choice sets.
A partial profile is a profile in a choice design where only a specified number of attributes are varied within each choice set. The remaining attributes are not varied.
In cases where many attributes are involved, you can construct surveys where each choice set contains partial profiles. In a choice set with partial profiles, only a specified number of attributes are varied and the remaining attributes are held constant. This reduces the complexity of the choice task.
