Level of measurement or scale of measure is a classification that describes the nature of information within the numbers assigned to variables.
Description
Psychologist Stanley Smith Stevens developed the best known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.
Other classifications include those by Chrisman and by Mosteller and Tukey.
This framework of distinguishing levels of measurement originated in psychology and is widely criticized by scholars in other disciplines.
