Frequently Asked Questions
What is a weighted average?
A weighted average is an average where each value contributes based on its assigned importance or weight.
Why not use a regular average?
A regular average treats every value equally. A weighted average is better when some values should count more than others.
Do values and weights need to match?
Yes. Each value needs one corresponding weight, so both lists must have the same number of entries.
