Median

From Latin “medianus” (of the middle), from “medius” (middle). Its statistical use was popularized in the 19th century, notably by Francis Galton, as a robust alternative to the average.

  1. noun · /MEE-dee-uhn/

    The middle value in a sorted list, with half the data above and half below.

    It gives a “typical” figure that a handful of giants or outliers cannot distort.

    Economists quote median household income rather than mean because a few billionaires would otherwise drag the “average” far above what most families see.

    When the mean and the median diverge sharply, the data are skewed — and whichever one a source chose to report often reveals the story it wanted to tell.

  2. noun · /MEE-dee-uhn/

    The strip of land, often planted or paved, dividing the two directions of a highway.

    the central divider of a road

    The car spun across three lanes and onto the median.

    Chiefly North American — literally the strip in the middle. Compare isthmus, another narrow dividing strip.
