FAQ
What is the difference between the mean, the median, and the mode?
The mean is the sum of all values divided by how many there are, the median is the middle value once the numbers are sorted, and the mode is the value that occurs most often. When the data contains extreme values, the median is usually more representative than the mean.
Can I enter decimals?
Yes. Any decimal works, such as 1.5, 2.7, or 3.14, and the results keep an appropriate number of decimal places.
What happens if the input contains non-numeric characters?
The tool skips anything it cannot parse as a number, calculates using only the valid values, and tells you which entries were skipped.
Is there a limit on how many numbers I can enter?
It handles large sets, typically several thousand values, which is plenty for everyday statistical work.
