Median in Czech

The northwestern Old Iranian language of the Medes, attested only by numerous loanwords in Old Persian, few borrowings in Old Armenian and some glosses in Ancient Greek; nothing is known of its grammar.

(statistics) Having the median as its value. [from 19th c.]

(statistics) A number separating the higher half from the lower half of a data sample, population, or probability distribution. The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median of {3, 3, 5, 9, 11} is 5). If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values. [from 19th c.]
