The term "arithmetic mean" is preferred in some contexts in mathematics and statistics, because it helps distinguish it from other means , such as the geometric mean and the harmonic mean. In addition to mathematics and statistics, the arithmetic mean is used frequently in many diverse fields such as economics , anthropology and history , and it is used in almost every academic field to some extent. For example, per capita income is the arithmetic average income of a nation's population. While the arithmetic mean is often used to report central tendencies , it is not a robust statistic , meaning that it is greatly influenced by outliers values that are very much larger or smaller than most of the values. For skewed distributions , such as the distribution of income for which a few people's incomes are substantially greater than most people's, the arithmetic mean may not coincide with one's notion of "middle", and robust statistics, such as the median , may provide better description of central tendency.

For example, we might put test scores in order, so that we can quickly see the lowest and highest scores in a group this is called an ordinal variable, by the way.
