To find the mean (also called the average) of a set of numbers, follow these simple steps:
-
Add all the numbers together.
Example: For the numbers 4, 7, and 10, add them up:
4 + 7 + 10 = 21 -
Count how many numbers there are.
In this example, there are 3 numbers. -
Divide the sum by the number of numbers.
So, 21 ÷ 3 = 7
The mean is 7.
Formula for the mean:
Mean=Sum of all numbersNumber of numbers\text{Mean}=\frac{\text{Sum of all numbers}}{\text{Number of numbers}}Mean=Number of numbersSum of all numbers
