Suppose we have sample space a 1 a 2 a n. The mean obtained by adding several quantities together and dividing the sum by the number of quantities. Suppose we are given n number of data and we need to compute the arithmetic mean all that we need to do is just sum up all the numbers and divide it by the total numbers.

A mean is commonly referred to as an average. Further equality holds if and only if every number in the list is the same. Arithmetic mean is a commonly used average to represent a data. Suppose we have sample space a 1 a 2 a n.
