Average Calculator

Find the mean, median, mode, sum and range of a list of numbers.

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.
