What 'average' means

The average, or arithmetic mean, sums all your values and divides by how many there are — the most common single number to summarise a data set. It's quick and intuitive, though it can be skewed by extreme values, in which case the median may describe the data better.

Frequently Asked Questions

How should I separate my numbers?

Any mix of commas, spaces, or new lines works — paste a column from a spreadsheet or type values inline and the calculator parses them.

Mean or median — which should I use?

Use the mean for balanced data. If a few outliers distort it, the median (middle value) often represents the typical value better.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
