About the mean, median and mode calculator
The mean, median and mode are three ways to describe the center of a data set. Paste or type your numbers, separated by commas, spaces or new lines, and all of them are calculated at once.
The mean is the sum divided by the count. The median is the middle value of the sorted list (or the average of the two middle values when the count is even). The mode is the value that appears most often. A list can have several modes, and when every value is unique there is no mode.
You also get the count, sum, minimum, maximum, range and the sorted list. The median is less affected by extreme values than the mean, so it is often a better description for skewed data such as incomes.
Formula
- Mean = sum of values ÷ number of values
- Median = middle value of the sorted list (average of the two middle values if n is even)
- Mode = most frequent value(s)
- Range = maximum − minimum
Example
For 12, 7, 3, 9, 7, 15, 3, 7 the sorted list is 3, 3, 7, 7, 7, 9, 12, 15. The mean is 63 ÷ 8 = 7.875, the median is 7, the mode is 7 and the range is 12.
