**Weighted Average**

A weighted average differs from an average in that a weighted average returns a number that depends on the variables of both value and weight.

**Formula**

Where,

w_{i} are weights and x_{i} are values

It is useful in many situations e.g., calculating average grade when the assignments carry different weights, calculating average shipping cost when the shipment consists of varying package size.
