Use the Average Calculator in three steps
Add the numbers
Separate values with commas, spaces, semicolons, or line breaks.
Let the list update
Valid numeric values are calculated as you type.
Use the right summary
Compare mean and median when outliers may affect the result.
Mean versus median
The mean divides the total by the count. The median is the middle sorted value and can better represent a typical result when a few numbers are unusually high or low.
Invalid fragments are ignored
Only values that can be read as finite numbers are included. Review the reported count to confirm that the expected number of entries was used.
