Nominal and ordinal data are part of the four data measurement scales in research and statistics, with the other two being an interval and ratio data. These four data measurement scales are subcategories of categorical and numerical data.
The Nominal and Ordinal data types are classified under categorical, while interval and ratio data are classified under numerical. This classification is based on the quantitativeness of a data sample.
Categorical data is a data type that not quantitative i.e. does not have a number. Therefore, both nominal and ordinal data are non-quantitative, which may mean a string of text or date.
What is Nominal Data?
Nominal data is defined as data that is used for naming or labelling variables, without any quantitative value. It is sometimes called “named” data - a meaning coined from the word nominal.
There is usually no intrinsic ordering to nominal data. For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.
What is Ordinal Data?
Ordinal data is a type of categorical data with an order. The variables in ordinal data are listed in an ordered manner. The ordinal variables are usually numbered, so as to indicate the order of the list. However, the numbers are not mathematically measured or determined but are merely assigned as labels for opinions.
