24

Sum

Quick answer

Average usually means arithmetic mean: sum divided by count.

Median is useful when outliers make the mean less representative.

Best inputs

Paste clean numeric values

Remove labels, currency symbols, and notes before calculating.

Check the detected count

The count helps confirm that every intended number was included.

Statistics method
The calculator parses numeric values and sorts them for median and range.
Mean = sum / count.
Median = middle sorted value or average of the two middle values.
Range = maximum - minimum.
Example, Assumption, and Limitation
Use the result as a practical estimate or transformation, then confirm edge cases for critical work.

Example

For 12, 18, 19, 24, 25, 25, 31, the mean is 22 and the median is 24.

Assumption

Only numeric values should be included in the input.

Limitation

This is descriptive math, not a full statistical analysis package.

Common use cases
