Weighted Average Calculator
The Weighted Average Calculator is an online tool designed to calculate the weighted average of a set of numbers, where each number has a corresponding weight or importance. This calculator is particularly useful in statistics, math, and education, where weighted averages are used to calculate grades, scores, and other metrics. By using this calculator, you can easily calculate the weighted average of a set of numbers, and understand how the weights affect the overall average.
Calculate the weighted average of a set of numbers.
How the Calculator Works
The Weighted Average Calculator uses a simple formula to calculate the weighted average of a set of numbers. The formula is: Weighted Average = (Value1 * Weight1 + Value2 * Weight2 +... + ValueN * WeightN) / (Weight1 + Weight2 +... + WeightN).
| Value | Weight | Weighted Value |
|---|---|---|
| 10 | 2 | 20 |
| 20 | 3 | 60 |
| 30 | 1 | 30 |
For example, if we have three values (10, 20, 30) with corresponding weights (2, 3, 1), the weighted average would be: (10 * 2 + 20 * 3 + 30 * 1) / (2 + 3 + 1) = (20 + 60 + 30) / 6 = 110 / 6 = 18.33.
