Mean, Median & Mode Calculator
Paste numbers to get mean, median, mode, range, count, and sum at once.
The three averages at a glance
Summarising a set of numbers usually starts with an average — but there are three, and they can tell very different stories. This calculator reports the mean, median, and mode together, plus the range, count, and sum, from any list you paste.
For 4, 8, 15, 16, 23, 42, 8 the mean is about 16.6, the median is 15, and the mode is 8. When the mean and median drift apart like this, it is a sign the data is skewed or has outliers.

Frequently Asked Questions
What is the difference between mean, median, and mode?
The mean is the average, the median is the middle value when sorted, and the mode is the most frequent value. Together they describe a data set from different angles.
When is median better than mean?
When data has outliers or is skewed — the median is not dragged by a few extreme values, so it often represents a typical value better.
Can there be more than one mode?
Yes. If several values tie for most frequent, the tool lists them all; if every value is unique, there is no mode.
