weighted mean formula

Let us learn about weighted mean formula

-->

Weighted mean is referred as the same as that of arithmetic mean. Where as each of the data is contributed uniformly with the weighed value. Incase all the weighted values are equal, and then the weighed mean is equal to the arithmetic mean. Weighted mean generally behaves similar fashion to the arithmetic mean. The term weighted average can also be known as weighted arithmetic mean or weighted harmonic mean.

• First calculate the sum for allocated weighted value & observed value.
• Second calculate the sum for all the observed values.
• Third make the division for the above 2 calculated values.
