Practical use cases and industry applications
Understanding Weighted Average
Average of values weighted by importance. Within math calculators, weighted average belongs to the statistics & probability cluster, where it shares terminology and assumptions with closely related tools.
Learning how weighted average is calculated
Weighted averages are used for grades, portfolio returns, and any scenario where items carry different importance. Working through the variables one at a time — weight — makes the result reproducible by hand and easier to sanity-check.
Using weighted average to make a decision
Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.
How weighted average compares with related measures
distribution, dispersion, significance, sample all describe adjacent aspects of statistics & probability. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
