Definition: Average refers to the sum of numbers divided by n. Also called the mean average.

Sums of data divided by the number of items in the data will give the mean average. The mean average is used quite regularly to determine final math marks over a term or semester. Averages are often used in sports: batting averages which means number of hits to number of times at bat. Gas mileage is determined by using averages.

Also Known As: Central tendency. A measure of the middle value of the data set.

Examples: If the average temperature this week was 70 degrees, the temperature would have been taken each day over the 7 days. Those temperatures would be added up and divided by 7 to determine the average temperature.
