Frequently Asked Questions
Common questions about the Mean, Median & Mode Calculator.
How do I use this calculator?
Paste or type your numbers separated by commas, spaces, or new lines, and the mean, median, mode, and more are calculated instantly.
What if my data set has more than one mode?
All tied modes are listed; if every value is unique, the tool states clearly that there is no mode.
Does it show the calculation steps?
Yes, the formulas and substitutions for mean and median are shown, including how the median is found for even- vs odd-sized data sets.
What's the difference between population and sample standard deviation?
Population SD divides by n and is used when your data is the entire group of interest; sample SD divides by n−1 and is used when your data is a sample used to estimate a larger population.
Can I paste data from a spreadsheet?

Does it handle decimals and negative numbers?

Is there a limit to how much data I can enter?
