Average Formula & Calculation Example
Average (x̄) = (x₁ + x₂ + x₃ + … + xₙ) ÷ n = (Σx) ÷ n
Example: Find the average of five exam scores: 78, 84, 91, 69, 88
Sum = 78 + 84 + 91 + 69 + 88 = 410
Count (n) = 5
Average = 410 ÷ 5 = 82
Frequently Asked Questions
Add all the numbers in your dataset together to get the Total Sum, and then divide that sum by the total Count of numbers: Average = Sum / Count.
The arithmetic mean is the sum divided by the count, whereas the median is the middle value when all numbers are sorted from smallest to largest. The median is less affected by extreme outliers.
Yes. Each input field accepts positive numbers, negative numbers, and decimal values.
