CalcCommonsHow to use
Enter the dataset using commas, spaces, or newlines. Calculate to sort the values and compare their mean, median, highest-frequency values, and range. Repeated entries are counted individually.

Formula & how it works
Mean = Σx/n. Median is the middle sorted value, or the mean of the middle two values. Modes share the highest frequency. Range = maximum − minimum.
Worked example
Example 1
For 2, 3, 3, 8: mean = 16/4 = 4, median = (3 + 3)/2 = 3, mode = 3, and range = 6.
Assumptions & practical notes
All entries carry equal weight. If every entry occurs once, this tool reports No mode.
Multiple values tied at a repeated maximum frequency are all listed as modes. The median is less affected by extreme values than the mean.
See our calculation methodology for unit definitions and testing practices.
Frequently asked questions
Can there be more than one mode?
Yes. In 1, 1, 2, 2, 3 both 1 and 2 are modes.
What happens with an even count?
The median is the arithmetic mean of the middle two sorted values.
