Mean, median or mode?

The mean adds everything and divides by the count; one very large value pulls it up. The median is the middle value when sorted — better for incomes and house prices. The mode is the most frequent value. For spread, see the Standard Deviation Calculator.

Frequently asked questions

How do I calculate a weighted average?
Multiply each number by its weight, add them up, and divide by the sum of the weights.
What if there is no mode?
If every value appears once, there is no mode; several values can also tie.
Is anything I enter saved or sent?
No. The calculation runs in your browser. Your last inputs are remembered on this device only, so the page opens where you left off.
Can I install Average Calculator as a web app and use it offline?
Yes. Average Calculator is an installable web app (PWA) — installed from your browser, not downloaded from an app store.
