Description: 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. Whereas weighted means generally behave in a similar approach to arithmetic means, they do have a few counter instinctive properties. Data elements with a high weight contribute more to the weighted mean than do elements with a low weight. The weights cannot be negative. Some may be zero, but not all of them; since division by zero is not allowed. Weighted means play an important role in the systems of data analysis, weighted differential and integral calculus.

Formula:

     x=w1x1+ w2x2+….+ wnxnw1 + w2 + ……+ wn

Example:  Enter the Weights to the X values = 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
