IconVault's Statistics Calculator turns any number list into a full set of descriptive statistics instantly. Paste comma, space or newline separated numbers and get count, sum, mean, median, mode and range, both sample and population standard deviation and variance, plus quartiles (Q1, Q3) and the interquartile range (IQR). A rendered box plot visualizes the spread, with whiskers for min and max and the median line through the box.

Percentiles use linear interpolation, the same method as NumPy's default, and any entries that are not numbers are skipped with the count shown. Copy all statistics as plain text for reports or spreadsheets. Everything runs fully in your browser, your data is never uploaded, and it is free to try.
