Brit.

/ˈkwɔːtʌɪl/, U.S.

/ˈkwɔrˌtaɪl/,

/ˈkwɔrdl/

Forms: late Middle English– quartile, 1500s quartyle.

Origin: A borrowing from Latin. Etymon: Latin quartilis.

Etymology: < post-classical Latin quartilis (c1270 in a British source in aspectus quartilis quartile aspect) < classical Latin quartus fourth (see quart n.²) + -īlis -il suffix. Compare Middle French, French quartile (1557). Compare later quintile adj., sextile adj.

A. adj.

Astrology and Astronomy. Designating the aspect of two celestial objects which are a quarter of a circle (90 degrees) apart in the sky; of or relating to such an aspect.

It will be seen that they correspond to the ill-named ‘probable errors’ of the ordinary theory.

1917 Amer. Naturalist 51 148 The ordinary expression for a probable error..gives the quartile limits (i.e. the limits within which one half the frequency occurs) on the assumption that the distribution is Gaussian.
