What this tool does
Type or paste any list of numbers, separated by commas, spaces or line breaks, and every basic summary is calculated at once. Seeing the mean next to the median is the quickest way to spot whether a few unusual values are skewing your data.
Formula
mean = (x₁ + x₂ + … + xₙ) ÷ n

Frequently asked questions
Should I use the mean or the median?
Use the mean when the values are fairly evenly spread, and the median when a few extreme values would distort the picture. Salaries are the classic case: one very high salary pulls the mean up, while the median still describes what a typical person earns. This tool shows both so you can compare them.
