FAQ
How do I calculate the mean, median and mode for free?
Paste your numbers separated by commas, spaces or new lines, and the mean, median and mode appear instantly in your browser with no upload — along with the min, max, range and standard deviation.
What's the difference between mean, median and mode?
The mean is the arithmetic average; the median is the middle value when sorted; the mode is the most frequent value. They can differ a lot when the data is skewed, which is why all three are shown.
Is my data uploaded?
No. Everything is computed on your device and nothing is stored; it works offline.
Does it handle decimals and negatives?
Yes — any real numbers, in any mix of separators.
Limits
Standard deviation is the population figure (dividing by n). Reports no mode when every value is unique.
