Mean 4 · Median 3The sum is 20 across five numbers. The value 10 raises the mean above the middle value.
General & Math
Mean & median calculator
About this tool
Summarize a set of scores, measurements or daily amounts in one calculation. The mean uses every value, while the median describes the middle of the sorted list, making it useful when an unusually large or small value skews the average.

Questions & answers
Does average mean the same thing as median?
Here, average means the arithmetic mean: sum divided by count. Median is the middle of the sorted list. A high outlier can change the mean substantially while changing the median very little.
Can I enter weighted values?
This tool gives each entered value equal weight. It does not calculate a weighted mean; enter repeated observations individually only when each occurrence is one observation.
