Mean, median and mode
- Mean: the sum of all values divided by how many there are.
- Median: the middle value when the numbers are sorted. With an even count, it is the average of the two middle values.
- Mode: the value that appears most often.
- Range: the difference between the largest and smallest value.
Which average should you use?
The mean works well for evenly spread data. When there are extreme values (like a few very high salaries), the median gives a better picture of the typical case.
Example
For 3, 7, 7, 9, 12, 15, 21: the sum is 74, the mean is 10.57, the median is 9 and the mode is 7.
Frequently asked questions
How do I enter the numbers?
Separate them with commas, spaces or line breaks. Decimals use a dot.
What if there is no mode?
If every value appears once, the tool shows 'None'.
Can there be several modes?
Yes, all values tied for the highest frequency are listed.
