Statistics

Average Calculator

Compute the arithmetic mean of a list of numbers.

Average (mean)

Sum

Count

Worked example

For 1, 2, 2, 3, 4, 5 the sum is 17 and n = 6, so the mean is 17/6 ≈ 2.833. That is the arithmetic mean, not the median (2.5) or the mode (2).

\[ \bar{x}=17/6\approx 2.833 \]

FAQ

Is this a sample mean or population mean?

The arithmetic mean formula is the same (sum / n). Sample versus population matters for variance and standard deviation on other statistics pages, not for this average.
