nominal scale parameters

discrete classification of data, in which data are neither measured nor ordered but subjects are merely allocated to distinct categories
NOTE: Nominal scaled parameters are applicable in Boolean equations using the operators equal or not equal.
EXAMPLE: A nominal scale parameter for vehicles could consist of cars, trucks, vans and motorcycles.
