# Arithmetic Mean

Definition: Arithmetic mean is also sometimes called the mean integral of a number sequence, the average of the integral of a set of numbers, or simply the average of a set of numbers. It is the fundamental statistic of statistics: it measures the average contribution in a weighted series of samples during a specified period. The mean is often defined as the average of one value in a series; it is the sum of the deviations from that average over all the values in the series. Mean differs from median and mode in that it is inclusive; that is, it includes the values for which the mean value is less than the corresponding value

In the realm of finance, there is a way to calculate an average based on data that comes from a large number of trials: that is, the arithmetic median. It is a useful tool and has many applications. However, it is often misleading, particularly when applied to small samples or situations with many different outcomes.

The Arithmetic Mean (AM) is one of the most important statistics you should learn. It has a lot of applications in areas like finance, statistics, and probability. It is a statistical measure of the average value of a set of numbers.
