Weighted Average

A weighted Average is a variant of an Average where some data points contribute more heavily to the output than others, as opposed to the equal spread of a regular Average.

$y=\frac{{\sum }_{i=1}^n{w}_i{x}_i}{{\sum }_{i=1}^n{w}_i}$ Where:

• $w$ is the list of weights for each point
• $x$ is the value of each point
