Level Of Measurement
The "levels of measurement", or scales of measure are expressions that typically refer to the theory of scale types developed by the psychologist Stanley Smith Stevens. Stevens proposed his theory in a 1946 Science article titled "On the theory of scales of measurement". In that article, Stevens claimed that all measurement in science was conducted using four different types of scales that he called "nominal", "ordinal", "interval" and "ratio", unifying both qualitative (which are described by his "nominal" scale) and quantitative (to a different degree, all the rest of his scales).

Famous quotes containing the words level and/or measurement:
“Your mock saint who stands in a niche is not a woman if she have not suffered, still less a woman if she have not sinned. Fall at the feet of your idol as you wish, but drag her down to your level after that—the only level she should ever reach, that of your heart.”
—Emmuska, Baroness Orczy (1865–1947)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
