Nominal Category
A nominal category or a nominal group is a group of objects or ideas that can be collectively grouped on the basis of a particular characteristic—a qualitative property.. A variable that codes whether each one in a set of observations is in a particular nominal category is called a categorical variable. Valid data operations A nominal group only has members and non-members. That is, nothing more can be said about the members of the group other than they are part of the group. Nominal categories cannot be numerically organized or ranked. The members of a nominal group cannot be placed in ordinal (sequential) or ratio form. Nominal categories of data are often compared to ordinal and ratio data, to see if nominal categories play a role in determining these other factors. For example, the effect of race (nominal) on income (ratio) could be investigated by regressing the level of income upon one or more dummy variables that specify race. When nominal variables are to be explained ...

Nominal Group (functional Grammar)
In systemic functional grammar (SFG), a nominal group is a group of words that represents or describes an entity, for example ''The nice old English police inspector who was sitting at the table with Mr Morse''. Grammatically, the wording "The nice old English police inspector who was sitting at the table with Mr Morse" can be understood as a nominal group (a description of someone), which functions as the subject of the information exchange and as the person being identified as "Mr Morse". A nominal group is widely regarded as synonymous with noun phrase in other grammatical models. However, there are two major differences between the functional notion of a ''nominal group'' and the formal notion of a ''noun phrase'' that must be taken into account. Firstly, the coiner of the term, Halliday, and some of his followers draw a theoretical distinction between the terms ''group'' and ''phrase''. Halliday argues that "A phrase is different from a group in that, whereas a group is an ex ...
