FAQ
What is a weighted average?
Each value contributes proportionally to its weight: multiply value by weight, sum, then divide by the total weight.
When does weighting matter?
Course grades where the final exam counts more than homework, or portfolio returns where positions have different sizes.
Can weights be decimals?
Yes — any non-negative weights work, including percentages that sum to 1 or credits that sum to any total.
