Toolstia / Average calculator
Calculate the average of numbers
Paste or type your numbers and get the average (mean), median, mode, range, sum, count and standard deviation straight away. Separate numbers with spaces, commas or new lines.
Enter some numbers to see the average and other statistics.
How it works
- Enter your numbers.
- Read the results as you type.
- Check any skipped entries.
Mean, median and mode
The mean adds up the numbers and divides by how many there are. The median is the middle value when sorted, and is less affected by one very large or small number. The mode is the value that appears most often.
Standard deviation
It shows how spread out the numbers are. Use the population version when your list is everything you care about, and the sample version when the list is only a part of a larger group.
No repeated value
If every number appears once there is no mode, and the tool says so instead of guessing. If several numbers tie, all of them are listed.
Bad entries
Anything that is not a number is skipped and listed above the results, so a typo does not silently change your answer.
