In statistics, there are four data measurement scales : nominal, ordinal, interval and ratio. It is a measurement mapping that preserves ordering, the size of intervals between the entities and the ratio between the entities. Male. Here the order of the set is fixed, but no arithmetic operation can be performed such as we know, rating 4 is better than 2, but two 2 ratings cannot be equaled to rating 4. ble scales, so also the nature of the underlying scales greatly limits the possible qualitative structures that give rise to such scales. Ordinal scale. Psychologist Stanley Stevens developed the four common scales of measurement: nominal, ordinal, interval and ratio. Administration time is between five and 15 minutes.

These are the Celsius, Fahrenheit, Kelvin , and Rankine scales. Interval Scale: All the data points which have been taken from some fixed interval set. Each of the four scales, respectively, typically provides more information about the variables being measured than those preceding it.
