Mean

How it works
The mean averages all values, the median is the middle of the sorted data, and the mode is the most frequent value. If every value occurs equally often, the dataset has no mode; tied highest frequencies produce multiple modes.
Worked example
For 1, 2, 2, 3, 4, the mean is 2.4, median is 2, mode is 2, and range is 3.

Frequently asked questions
What happens with invalid or incomplete inputs?
The result remains blank until the required inputs form a finite, meaningful calculation. Zero denominators and physically impossible negative quantities are not calculated.
Can I use decimal values?
Yes. The tool accepts decimals and keeps full precision for the calculation while rounding the displayed result for readability.
