### How to calculate the Weighted Mean?

To calculate the weighted mean, sum the result of every**value**multiplied by a

**weight**and divide it by the

**sum of all weights**.

**Example:**

We have two values: 2, and 5. The 2 weigh 4, and the 5 weigh 20.

**Weighted Mean** = (2 * 4 + 5 * 20) / (4 + 20) = (8 + 100) / 24 = 108 / 24 = 4.5
