Mean Median Mode Calculator
Get the mean, median, and mode of a data set at once, plus the count and range.
How it works
The three averages tell different stories. The mean is the arithmetic average, the median is the middle value, and the mode is the most common — and on skewed data they can be strikingly far apart.
This computes all three at once from a list you paste in, so you can see, for instance, how one huge outlier drags the mean away from the median while the mode ignores it entirely.
It also reports the count and range for context, and it handles data sets with more than one mode rather than silently picking one.
Frequently asked questions
What is the difference between mean, median, and mode?
Mean is the sum divided by the count, median is the middle value when sorted, and mode is the value that appears most often. Each summarizes the data differently.
When should I use the median instead of the mean?
Use the median when the data has outliers or is skewed, like incomes or house prices, because a few extreme values distort the mean but not the middle.
Can a data set have more than one mode?
Yes. If two or more values tie for most frequent, the set is multimodal and this tool lists all of them rather than choosing one.
