Category

Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::Conceptual::Category

Definition

Concept whose role is to define and measure a characteristic.

Examples

The category “Male” is used to define or measure “Sex” or “Gender”, which are characteristics. In turn, they are also variables. “Extremely Satisfied” is a category in an agreement scale. This can be used for many kinds of variables.

Explanatory notes

A category is a concept, typically associated with a code in the representation of a variable value. Categories are most often used in the allowed values for qualitative, i.e., nominal and ordinal, variables. A set of categories, say “Male” and “Female” for characteristics “Sex” or “Gender,” helps define those characteristics. For describing location of measurement station, you might have categories “Urban”, “Suburban”, “Rural”, etc.
