Mean Median Mode Calculator

Find the mean, median, modes, sum and range of up to 10000 numbers. Paste values separated by spaces, commas or newlines and inspect the summary.

Supply observations

Enter 2, 4, 4, 6, 9. The count is five, the sum is 25 and the arithmetic mean is 5.

The median uses sorted values. For an even count, it averages the two central observations.

All values tied for the highest repeated frequency are returned as modes. A sample without repetitions returns an empty mode list.

These are unweighted descriptive statistics. Commas separate observations, so write one thousand as 1000 rather than 1,000.

Does the calculator accept missing observations?

Remove missing-value markers such as N/A. Every supplied token must be a finite number.

Why can the mean differ from the median?

A very large observation pulls the mean upward while the median depends on the middle positions of the sorted sample.
