Calculates the arithmetic average of a list of numbers, useful for grades, metrics and analyses.
How to calculate the arithmetic mean
UtilNexo's calculator finds the arithmetic mean of a list of numbers by adding them all and dividing by the count.
The formula is simple: mean = sum of values ÷ number of values. For grades 7, 8, and 9, the sum is 24 and the mean is 24 ÷ 3 = 8.
The arithmetic mean is used in school grades, indicators, statistics, and everyday analysis. Just paste the numbers separated by comma, space, or line.
Examples
- 7, 8, 9 → 8.
- 10, 20, 30, 40 → 25.
Limitations
- The mean is sensitive to extreme values (outliers), which can distort perception.
- For values with different weights, use the weighted mean, which considers the importance of each item.
