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.
