Mean Median Mode Calculator

This calculator works out the mean, median and mode of a list of numbers along with the full five number summary. Type the values separated by commas or spaces, and it returns the minimum, first quartile, median, third quartile and maximum, plus the range, the interquartile range and the midrange. It also flags any value that sits more than 1.5 interquartile ranges beyond the nearest quartile, which is the usual test for an outlier. Quartiles have several competing definitions that disagree on small samples, so the method used here is named with the result.
