About this calculator
An average summarizes a set of numbers in one value. This tool reports the arithmetic mean, plus median, sum, count, and range so you can see both the typical value and the spread.
How to calculate
Enter numbers separated by commas, spaces, or new lines. Empty entries are ignored. The calculator then returns the mean and supporting statistics.
Mean = (x₁ + x₂ + … + xₙ) / n
Median = middle value after sorting
Examples
Simple mean
The numbers 2, 4, and 6 have a mean of (2 + 4 + 6) / 3 = 4.
FAQ
What is the difference between mean and median?
The mean is the sum divided by the count. The median is the middle value after sorting, so a few extreme numbers affect it less.
Can I paste a column of numbers?
Yes. Separate values with commas, spaces, or line breaks. Invalid tokens are reported instead of silently ignored.
