About this calculator

The arithmetic mean is the balance point of a dataset. When outliers distort it — one billionaire walks into a bar and everyone's 'average' wealth explodes — compare with the median, which this tool shows alongside.

Formula

Mean = Σ values ÷ count of values

Frequently Asked Questions

Mean vs median — when to trust which?

Use median for skewed data: incomes, house prices, response times. Mean suits symmetric data like measurement errors.

Can I paste from Excel?

Yes — tab-separated pastes usually survive; ensure values remain separated by commas/spaces after pasting.
