# Average Formula

Average is also known as the arithmetic mean. Average is defined as the sum of all the observations divided by the total number of observations.

**If $x_{1}$, $x_{2}$, $x_{3}$, $x_{4}$..., $x_{n}$ are the set of observations, then**

Average = $\frac{x_{1} + x_{2} + x_{3} + x_{4}...+ x_{n}}{n}$.

**Where, n is the total number of observations.**
