| median |
the midpoint in a series of numbers; half the data values are above the median, and half are below. For example, in the odd series 1, 4, 9, 12 and 33, 9 is the median. In the even series 1, 4, 10, 12, 33 and 88, 11 is the median (halfway between 9 and 12). Note, the median is not necessarily the same as the AVERAGE (or mean). For example, the median of 2, 6, 10, 22 and 40 is 10 but the average is 18.
