Average Calculator

Enter your list of numbers separated by commas or spaces (e.g., 10, 20, 30, 40, 50). The calculator instantly computes: - Arithmetic Mean: sum of all values divided by count - Median: middle value when sorted - Mode: most frequent value(s) - Geometric Mean: nth root of the product of all values - Harmonic Mean: reciprocal average

For a weighted average, click 'Add Weights' and enter a matching list of weights. Use the preset examples (Test Scores, Prices, etc.) to explore quickly.

Arithmetic Mean = Σx / n

Median = middle value of sorted data (or average of two middle values if n is even)

Mode = most frequently occurring value (may have multiple modes or none)

Geometric Mean = (x₁ × x₂ × … × xₙ)^(1/n)

Harmonic Mean = n / (Σ(1/xᵢ))

Weighted Mean = Σ(wᵢ × xᵢ) / Σwᵢ

Use arithmetic mean for symmetric data; geometric mean for rates/ratios; harmonic mean for speeds/rates; weighted mean when items have different importance.
