Nominal Scale

A Nominal Scale is a measurement scale that identifies things using a word. Also known as a qualitative scale, items are usually organized by their category or name. There is no order or ranking in this type of scale. Some examples of nominal categories are gender (male and female) and ethnicity (Caucasian, African-American, Hispanic, Asian, etc.). For example, in an experiment using using student volunteers several nominal scales could be used to create different books. The students could be categorized by gender, age, or what year in school they are.
