Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal , ordinal , interval , and ratio .
One of his most influential contributions was his definition of a measurement scale defined by four types: Nominal, Ordinal, Interval, and Ratio.

The principal methods used by Stevens to measure the perceived intensity of a stimulus were magnitude estimation and magnitude production. In magnitude estimation with a standard, the experimenter presents a stimulus called a standard and assigns it a number called the modulus. For subsequent stimuli, subjects report numerically their perceived ...
Psychometrics deals with measurement of psychological attributes. It involves developing and applying statistical models for mental measurements. [ 2 ] The measurement theories are divided into two major areas: (1) Classical test theory ; (2) Item Response Theory .
