The value obtained by dividing the sum of a set of quantities by the number of quantities in the set. Also called average.

arithmetic mean

n
(Mathematics) an average value of a set of integers, terms, or quantities, expressed as their sum divided by their number: the arithmetic mean of 3, 4, and 8 is 5. Often shortened to: mean Also called: average Compare geometric mean

ar′ithmet′ic mean′


n.
the mean obtained by adding several quantities together and dividing the sum by the number of quantities: The arithmetic mean of 1, 5, 2, and 8 is 4. Also called average.

ar·ith·met·ic mean

(ăr′ĭth-mĕt′ĭk)
The value obtained by dividing the sum of a set of quantities by the number of quantities in the set. For example, if there are three test scores 70, 83, and 90, the arithmetic mean of the scores is their sum (243) divided by the number of scores (3), or 81. See more at mean. Compare average, median, mode.
