Summary

1. Weighted Mean: A mean where some values contribute more than others.
2. When the weights add to 1: just multiply each weight by the matching value and sum it all up.
3. Otherwise, multiply each weight w by its matching value x, sum that all up, and divide by the sum of weights: Weighted Mean = ΣwxΣw.
