Average, also called the mean, is calculated by adding all values together and dividing the total by the number of values.
Average calculations are widely used in academic grading, statistics, finance and performance evaluation.
Average = (Sum of Values) ÷ (Total Number of Values)
Average of 10, 20, 30
(10 + 20 + 30) ÷ 3 = 20
The average is the central value obtained by dividing the total sum of numbers by the count of numbers.
Add all numbers together and divide the result by the total number of values.
