ISBN978-0-521-54478-8. „When we come to quantities like IQ or g, as we are presently able to measure them, we shall see later that we have an even lower level of measurement—an ordinal level. This means that the numbers we assign to individuals can only be used to rank them—the number tells us where the individual comes in the rank order and nothing else.“
Mackintosh, N. J. (1998). IQ and Human Intelligence. Oxford: Oxford University Press, გვ. 30–31. ISBN0-19-852367-X. „In the jargon of psychological measurement theory, IQ is an ordinal scale, where we are simply rank-ordering people. ... It is not even appropriate to claim that the 10-point difference between IQ scores of 110 and 100 is the same as the 10-point difference between IQs of 160 and 150“
