Weighted average calculator and calculation. Weighted mean calculator.

The weighted average (*x*) is equal to the sum of the product of the weight (w_{i}) times the data number (x_{i}) divided by the sum of the weights:

Find the weighted average of class grades (with equal weight) 70,70,80,80,80,90:

Since the weight of all grades are equal, we can calculate these grades with simple average or we can cound how many times each grade apear and use weighted average.

2×70,3×80,1×90

*x* = (2×70+3×80+1×90) / (2+3+1) = 470 / 6 = 78.33333
