Enter or paste numbers separated by commas, spaces or new lines to instantly get the mean, median, mode, range, sum, count, minimum, maximum, sample and population standard deviation, and geometric mean.
How to calculate an average
- Paste or type your numbers.
- Read the mean (average), median and mode.
- Use standard deviation to see how spread out the values are.
Mean, median or mode?
The mean adds all values and divides by the count. The median is the middle value when sorted, which is less affected by outliers (useful for salaries and house prices). The mode is the most frequent value.
Frequently asked questions
Sample or population standard deviation?
Use sample (divide by n − 1) when your numbers are a sample of a larger group; use population when you have every value.
