1875 F. Galton in London, Edinb. & Dublin Philos. Mag. 4th Ser. 49 37 We may work backwards, and, from the relative frequency of occurrence of various magnitudes, derive a knowledge of the true relative values of those magnitudes, expressed in units of probable error.

1955 M. Loève Probability Theory i. 5 In a game of dice..‘double-six’ occurs about once in 36 times, that is, its observed frequencies cluster about 1/36. The number 1/36 is a permanent numerical property of ‘double-six’ under the conditions of the game, and the observed frequencies are to be thought of as measurements of the property.
