Worksheet to find Weighted Mean
This worksheet may help you to know about the Weighted Mean. Weighted Mean is an average calculated 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. The weights cannot be negative. The formula used to calculate weighted mean is, Weighted Mean FormulaWhere x is the repeating value w is the number of occurrences of x (weight) x̄ is the weighted mean Weighted Mean ExampleX = 5,20,40,80,100 Weighted mean = (W1X1+W2X2+W3X3+...WnXn)/(W1+W2+W3+...Wn) Weighted mean = (5+40+120+320+500)/ (5+20+40+80+100) Weighted mean = ( 985) /(245) Weighted mean = 4.020408163265306 Weighted mean (rounded) = 4.0204 The above worksheet is a walk through to understand How to calculate weighted mean value for the given data. When it comes to online calculator this Weighted Mean Calculator is an essential tool to make the calculation easy.
