Definition

A familiar but elusive concept. Generally, an “average” value purports to represent or to summarise the relevant features of a set of values; and in this sense the term would include the median and the mode. In a more limited sense an average compounds all the values of the set, e.g. in the case of the arithmetic or geometric means. In ordinary usage “the average” is often understood to refer to the arithmetic mean.
