DERIVATIVES: av·er·age·ly adv. ORIGIN: late 15th cent.: from French avarie ‘damage to ship or cargo,’ earlier ‘customs duty,’ from Italian avaria, from Arabic 'awār ‘damage to goods’; the suffix -age is on the pattern of damage. Originally denoting a charge or customs duty payable by the owner of goods to be shipped, the term later denoted the financial liability from goods lost or damaged at sea, and specifically the equitable apportionment of this between the owners of the vessel and the cargo (late 16th cent.); this gave rise to the general sense of the equalizing out of gains and losses by calculating the mean (mid 18th cent.).

Other calculations that are also used to express what is typical in a set of scores are the mode (the one score that occurs most often), and the median (the middle score in a range which thus divides the set of scores into upper and lower halves).
