Frequently asked questions

How do you calculate an average (mean)?
Add all numbers, then divide by how many numbers you have. Mean = sum / count.
Is average the same as median?
No. Mean is the arithmetic average; median is the middle value after sorting. Use the median calculator for that.
How should I enter the list?
Separate numbers with commas or spaces. Non-numeric tokens are ignored.
Does order matter?
Order does not change the mean. Empty lists are rejected.
Can I include decimals and negatives?
Yes. Decimals and negative values are valid. Only non-numeric tokens are skipped.
When should I use median instead?
If outliers skew the mean (one huge value), the median often describes the “typical” value better.
