Average Calculator
Paste or type a list of numbers to get the mean, median, mode, and other summary statistics instantly.
Overview
"Average" usually means the mean, but the mean can be misleading on its own — a single outlier skews it, while the median (the middle value) doesn't. This tool computes both, plus the mode (most frequent value), minimum, maximum, sum, and count from one list, so you can see the fuller picture rather than a single number.
Examples
Simple list
4, 8, 6, 5, 3
Mean: 5.2, Median: 5
With an outlier
10, 12, 11, 13, 90
Mean: 27.2, Median: 12
How It Works
- Paste or type numbers separated by commas, spaces, or new lines.
- The mean, median, mode, minimum, maximum, sum, and count appear instantly.
Use Cases
Grade averaging
Find the mean and median of a set of test or assignment scores.
Spotting skew
Compare the mean against the median to see whether outliers are pulling the average up or down.
Tips
- If the mean is noticeably higher or lower than the median, that's a sign the list has one or more outliers pulling the mean in that direction.
FAQ
No. Every calculation runs locally in your browser.
If every value appears the same number of times, the tool reports that there's no unique mode rather than listing every value.
Yes — both are fully supported in the input list.
