For example, if a nominal variable has three categories (A, B, and C), two dummy variables would be created (for A and B) where C is the reference category, the nominal variable that serves as a baseline for variable comparison. [6]
In linguistics, the term nominal refers to a category used to group together nouns and adjectives based on shared properties. The motivation for nominal grouping is that in many languages nouns and adjectives share a number of morphological and syntactic properties.
In statistics, a categorical variable (also called qualitative variable) is a variable that can take on one of a limited, and usually fixed, number of possible values, assigning each individual or other unit of observation to a particular group or nominal category on the basis of some qualitative property.

A nominal scale consists only of a number of distinct classes or categories, for example: [Cat, Dog, Rabbit]. Unlike the other scales, no kind of relationship between the classes can be relied upon. Thus measuring with the nominal scale is equivalent to classifying.
This is a list of statistical procedures which can be used for the analysis of categorical data, also known as data on the nominal scale and as categorical variables. General tests [ edit ]
A grammatical case is a category of nouns and noun modifiers (determiners, adjectives, participles, and numerals) that corresponds to one or more potential grammatical functions for a nominal group in a wording.
