Find the mean, median, mode, sum and range of a list of numbers.
Calculated live in your browser.
Understanding your result
The mean is sensitive to outliers, while the median is more robust. The mode highlights the most common value, if any.
Formula and method
Mean = sum ÷ count. Median = the middle value when sorted (average of the two middle values for an even count). Mode = the most frequent value. Range = max − min.
Worked example
For 10, 20, 30, 40 the mean is 25, the median is 25, the sum is 100 and the range is 30.
