Frequently Asked Questions
How is weighted average calculated?
Weighted Average = Σ(value × weight) ÷ Σ(weight) — each value is multiplied by its weight, summed, then divided by the total of all weights.
How is this different from a regular average?
A regular (simple) average treats every value equally. A weighted average lets you give some values more importance than others, based on the weight you assign.
