#### What is weighted mean?

Weighted Mean is an average computed by giving different weights to some of the individual values. If all the weights are equal, then the weighted mean is the same as the arithmetic mean. It represents the average of a given data. The Weighted mean is similar to the arithmetic mean or sample mean.

#### How to do weighted mean?

Mean. When we do a simple mean (or average),we give equal weight to each number.
