Example Weighted Average Calculations We’ll start with an example where the weights sum to one. This situation frequently occurs when someone intentionally builds the weighted average into a process. For example, a teacher might devise a grading system using weights and, for simplicity, has the w...
Weighted average is the summation of the product of the weights and quantities, divided by the summation of the weights. How to Calculate Weighted Average? We use the following weighted average formula for calculation. ¯¯¯x=w1x1+w2x2+...+wnxnw1+w2+...+wnx¯=w1x1+w2x2+...+wn...
The definition of a weighted average (also known as a weighted mean) is a calculation that measures the average of a data set in which certain numbers, or values, may be more important than others. These types of data sets may be found in businesses, sports, schools, etc. For example,...
The term “weighted average” refers to an average in which each quantity is to be averaged given a weight. A weighted average computation accounts for the varying numbers’ significance levels in a data collection. When calculating a weighted average, a specified weight is multiplied by each val...
A weighted average is an average where each value has a different level of importance, represented by a weight, which affects the overall calculation. Contents: 1. Formula 2. Example - Calculating Weighted Average Grades Weighted Average Formula The weighted average formula in Excel is the foll...
As you can see in the screenshot, the formula returns exactly the same result as the calculation we did a moment ago. Notice the difference between the normal average returned by the AVERAGE function (C8) and weighted average (C9). Although the SUM formula is very straightforward and easy ...

Average calculator ►Weighted average calculationThe weighted average (x) is equal to the sum of the product of the weight (wi) times the data number (xi) divided by the sum of the weights:ExampleFind the weighted average of class grades (with equal weight) 70,70,80,80,80,90:...
For example, when calculating the average grade of a student, a weighted average would be used if different assignments or exams have different point values. In this case, the grades on assignments or exams with more points would carry more weight in the final calculation of the average grade...
Different values have different weights, and the calculation is made by multiplying each weight with its corresponding value. The summation of all of them is divided by the sum of the weights. However, the choice between them depends on the type of information being dealt with. The Average ...
