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.
