Formula and methodology
Formula: Weighted average = Σ(value × weight) / Σweight.
Each value contributes in proportion to its weight, so the total weight must be positive and the two lists must have matching lengths.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Values — Enter comma-separated numbers.
- Weights — Enter one nonnegative weight for each value.
Worked example
| Input | Value |
|---|---|
| Values | 10, 20, 30 |
| Weights | 1, 2, 1 |
Weighted average = 20.
Assumptions and limits
- Values and weights are comma-separated finite numbers.
- Weights are nonnegative and at least one weight is positive.
- The result is a descriptive weighted mean, not a statistical uncertainty estimate.
