Hello Boys and Girls,

The mean, also called average, is a measure of the central tendency of a group of values. When we are asked to calculate the mean, we are asked to calculate the central value of a set of numbers.

To calculate the mean, we perform two operations: addition (+) and division (÷).

Here are the steps:

- Find the sum up all the numbers

- Divide the sum by the number of values/addends/items
