Frequently asked questions
How do I enter my numbers?
Type or paste them separated by commas, spaces, or line breaks — e.g. 2, 4, 6. The calculator ignores anything that isn't a number.
Is this the mean or the median?
This is the arithmetic mean — the sum divided by the count. For the median and mode too, use our Mean Median Mode Calculator.
Can I average decimal numbers?
Yes. Decimals like 9.5, 8.25, 7.75 work fine, and the average keeps full precision.
