Mean Calculator — Average of a Number List
Calculate arithmetic, geometric, or harmonic mean from a number list with a clear formula path. Example: 1,2,3,4,5 arithmetic → 3. Browser-only; pick the mean type that matches your process.
How it works
Paste numbers separated by commas or spaces, choose arithmetic / geometric / harmonic, then calculate.
Formula
Ā = (Σx)/n; G = (Πx)^(1/n); H = n / Σ(1/x). Notes:
- Geometric mean needs every value > 0.
- Harmonic mean rejects zeros.
- Pair with median / SD tools for distribution drills.
Example
Example: 1,2,3,4,5 arithmetic → 3.
When to use it
