Which data scale is used to categorize data by type without numerical meaning?

Explanation:
Nominal data are categories used to label or classify without implying any order or magnitude. The numbers assigned are just codes and have no mathematical meaning, so data can be sorted into types like blood type, eye color, or species without suggesting more or less. This differs from ordinal data, which adds a sense of order; interval data, which has equal intervals but no true zero; and ratio data, which has both equal intervals and a true zero. So categorizing data by type without numerical meaning is a hallmark of nominal data.
