Weighted Average Calculator
Weighted Average: a planned Super Calculator tool. Covers value and weight pairs. Stub page: the tool, its formula and a worked example are not published yet.
Weighted Average Calculator is a planned calculator in the mathematics section of Super Calculator, covering descriptive and summary statistics.
What this calculator will compute
Inputs: value and weight pairs and weight normalization behavior.
Outputs: weighted average, sum of weights, each item contribution and unweighted mean for comparison.
Formula, recorded as scope and not yet verified against a primary source: Weighted mean = sum(w_i x_i) / sum(w_i). Weights need not sum to one; normalizing them is the implementation detail users get wrong when weights are given as percentages that do not total 100%.
