What is another word for geometric mean?
Pronunciation: [d͡ʒˌiːə͡ʊmˈɛtɹɪk mˈiːn] (IPA) 
The geometric mean is a mathematical concept used to determine the central tendency of a set of values. Other terms that refer to this concept include the logarithmic mean, the geo-average, and the geometric average. It can also be described as the nth root of the product of n values, where n is the number of values in the set. The geometric mean is different from the arithmetic mean, which is the sum of a set of values divided by the number of values in the set. While the arithmetic mean is used to determine the average of simple or linear data, the geometric mean is used for data that varies exponentially or geometrically.
