Average

In mathematics, there are numerous methods for calculating the average or central tendency of a list of n numbers. The most common method, and the one generally referred to simply as the average, is the arithmetic mean. Please see the table of mathematical symbols for explanations of the symbols used.

Etymology

Average is derived from Romance avaria, a 'tax'; this is in turn connected with the Arabic or Turkish avaria or avania of the same meaning. The OED considers it uncertain which is older. If the Italian and related forms are not from the Arabic, they may be from Italian avere, 'goods'.
