WEIGHTED ARITHMETIC MEAN ✅ STATISTICS
The weighted arithmetic mean is calculated by multiplying each value in the data set by its weight. Then, the sum of these values is found and divided by the sum of the weights.
What is a weighted average examples?
Definition of weighted arithmetic mean
In other words, we add the products of the values by their weights and divide the result by the sum of the weights. Example: Alcebíades participated in a competition, where tests were held in Portuguese, Mathematics, Biology and History. These tests had weights of 3, 3, 2 and 2, respectively.

What is the Weighted Average Calculation For?
The weighted average is important for calculating data that has different numbers or weights of values. Through this calculation, it is possible to obtain an average that shows the panorama of a given scenario.
How is the weighted average calculated?
To calculate the weighted average, follow these guidelines: Multiply the information whose average needs to be calculated by their respective weights; 2 – Add the results of these multiplications; 3 – Divide the result obtained by the sum of the weights used.
