The arithmetic mean (often referred to as the average, arithmetic average, or the mean) is a value indicating the typical value of the elements in a given data set. It is computed by summing the numbers in a data set and dividing that number by the amount of numbers in the set.$$\overline{x} = \frac{1}{n}\sum_{i=1}^{n}{x_i}$$ where $x_i$ represents the individual values and $n$ represents the number of values in the data set.

The arithmetic mean of $1, 5, 7, 11, 12,...$ is $\frac{89}{8} = 11.125$.
