How to use the average calculator
- Type or paste your numbers in the box. Commas, spaces and line breaks all work.
- The results update as you type.
- Read the mean, median, mode, range, sum and standard deviation.
Mean, median and mode
- Mean (average): the sum of all numbers divided by how many there are.
- Median: the middle number when the list is sorted. With an even count it is the average of the two middle numbers.
- Mode: the number that appears most often.
- Range: the highest value minus the lowest.
The median is better than the mean when a few values are extremely high or low.

The mean is the arithmetic average. The median is the middle value, which is less affected by very large or very small numbers.
What if no number repeats?
Then there is no mode and the tool shows "None".
What is the difference between the two standard deviations?
Use population when your list is the entire group, and sample when it is only a part of a larger group.
