Average / Mean Calculator
Paste or type a list of numbers and instantly get the full set of basic statistics: the mean (average), the median (middle value), the mode (most frequent value), the range, the sum and the count. Numbers can be separated by commas, spaces or new lines, so you can drop in data straight from a spreadsheet or a note. Seeing mean and median together is especially useful because when they differ a lot it tells you the data is skewed by outliers. This is handy for grades, prices, measurements, survey results or any quick data check. The calculation is exact and updates as you edit the list, running entirely in your browser so your numbers never leave your device.
