Calculating the weighted average is a common task in various fields such as finance, statistics, and academics. This calculator simplifies the process, providing a quick and efficient way to determine the weighted average of a set of values.
Formula: The weighted average is calculated by multiplying each value by its corresponding weight, summing these products, and then dividing by the total weight.
How to Use:
- Enter the weights, separated by commas, in the first input box.
- Enter the values, separated by commas, in the second input box.
- Click the "Calculate" button to obtain the weighted average.
Example: Suppose you have three values (10, 15, 20) with corresponding weights (0.2, 0.3, 0.5). Enter these values and weights, click "Calculate," and the result will be displayed.
