Measurement scales are used to categorize andor quantify variables. This lesson describes the four scales of measurement that are commonly used in statistical analysis: nominal, ordinal, interval, and ratio scales. Each scale of measurement satisfies one or more of the following properties offour types of measurement scales: (1) nominal, (2) ordinal, (3) interval, and (4) ratio. Nominal Scales The word nominal is derived from nomen, the Latin word for name. scales of measurement statistics pdf

measurement, and Michell (1986) (developed further in Michell (1990)) contrasted. representational theory, operational theory and classical theory. Michell, in fact, described the controversy over scales of measurement as a 'clash of. paradigms' making the parallel

temperature scale is a ratio scale, not only can we say that a temperature of 200 degrees is higher than one of 100 degrees, we can correctly state that it is twice as high. Interval scales do not have the ratio property. Most statistical data analysis procedures do not distinguish between the interval and ratio properties of the measurement scales.

The Fahrenheit scale is a clear example of the interval scale of measurement. Thus, 60 degree Fahrenheit or 10 degrees Fahrenheit are interval data. Measurement of Sea Level is another example of an interval scale. With each of these scales there is direct, measurable quantity with equality of units. In his seminal paper On the theory of scales of measurement (1946), Stevens presents a hierarchy of data scales based on invariance of their meaning under different classes of transformations. The scale type takes its name from the fact that measurement is the estimation of the ratio between a magnitude of a continuous quantity and a unit magnitude of the same kind (Michell, 1997, 1999). Descriptive Statistics Scales of Measurement Level of Measurement. The Four Scales of Measurement. Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio. Each level of measurement has some important properties that are useful to know.
