The average ¹ or mean ¹ most frequently used in demography is the arithmetic average ² or arithmetic mean ² which consists of the sum of a series of quantities divided by their number.. Where the term average or mean is used without further qualification the arithmetic average is generally meant. The geometric mean ³ or geometric average ³ is sometimes used when all observed values are positive. It is the Nth root of the product of N values. A weighted average ⁴ or weighted mean ⁴ is obtained when different items are given varying importance by multiplying each item by a particular weighting factor ⁵ or weight ⁵. The median ⁶ is the value of the element which divides a set ⁷ of observations into two halves. The mode ⁸ is the most common or frequent value in a set of observations.

1. Average, n., can be used as an adjective. Mean, n., can be used as an adjective.
5. Weight, n. - weigh, v.
6. Median, n., can be used as an adjective.
8. Mode, n., modal, adj.
