A measuring system in which the numbers used do not reflect the magnitude of the objects being measured. The numbers serve only to label or classify, not to order in any way.
A scale in which responses are ordered only into different categories. See also categorical scale, interval scale, ordinal scale, and ratio scale.
A scale that uses groupings instead of ranking (scoring, numbering). For example, eye color could be grouped by “blue,” “brown,” or “green,” not given different numbers. Other groupings used on a nominal scale could be by diagnosis, age, sex, or race.
The approximate or intended scale of a photograph. This is typically the scale which was being sought, though the actual scale of any given photograph or portion of a photograph may vary somewhat.
A measurement scale that involves categorizing cases into two or more distinct categories.
A measurement scale in which numbers are used to classify, name or label an individual, attribute or category. The numbers have no specific order or importance. Nominal scales are often used to designate group membership (such as male, female, race/ethnicity, socioeconomic status). Nominal scales are also used to indicate characteristics that individuals do and do not have (such as a diagnosis of anxiety disorder, a family history of schizophrenia).
a qualitative categorization according to unordered distinctions
a set of categories that have no set order or hierarchy of values
Data is allocated into different (often named or numbered) categories. For example, the allocation of books in a library catalogue to different topics. Data on this scale cannot be meaningfully added and subtracted.
A measurement scale in which numbers are assigned to attributes of objects or classes of objects solely for the purpose of identifying the objects.
The nominal scale is a scale that can be used to classify data into mutually exclusive and exhaustive categories.
A classification of cases which defines their equivalence and non-equivalence, but implies no quantitative relationships or ordering among them. Analytic techniques appropriate for nominally scaled variables are not affected by any one-to-one transformation of the numbers assigned to the classes. See also SCALE OF MEASUREMENT.
A nominal (or categorical) scale is one in which the values are distinct categories, eg male or female. It has the property of distinctiveness of the values, but not ordering, equidistant intervals or an absolute zero.
Classification into unordered qualitative categories; e.g., race, religion, and country of birth as measurements of individual attributes are purely nominal scales, as there is no inherent order to their categories.
A nominal scale contains mutually exclusive categories identified by names.
a scale of measurement that places objects, individuals, or characteristics into categories. (641)
A scale of measurement that consists of categories, such as sex, birth place, type of sport one enjoys playing, and so on.
The simplest scale of measurement. It is used for characteristics that have no numerical values (examples are race and gender). It is also called a categorical or qualitative scale.
The actual scale (no rectification) at which photography is flown.
(n) A qualitative data scale that has no inherent order to it (e.g., New York, Boston, and Houston).
