What is the Weighted Mean Calculator?

The Weighted Mean Calculator computes the average of a set of numbers where each value has a different level of importance or weight. Unlike the simple mean, the weighted mean multiplies each value by its corresponding weight, sums these products, and then divides by the sum of the weights. This calculator also provides a step-by-step table showing each value, its weight, the product of value and weight, and the totals used to compute the weighted mean.

How to Use:

1. Enter Values: Provide the numbers you want to average, separated by commas (e.g., 10, 20, 30, 40).
2. Enter Weights: Provide the corresponding weights for each value, also comma-separated (e.g., 1, 2, 3, 4).
3. Click “Calculate”: The calculator multiplies each value by its weight, sums the products, divides by the total weights, and gives the weighted mean.
4. View Table: A table displays each step, including each product and totals, making the calculation transparent.
