Enter any list of numbers to get the mean, along with the median, sum, count, smallest, largest, and range.
The mean adds every value and divides by how many there are.
The median sorts the values and takes the middle one — or the average of the two middle ones when the count is even.
The range shows how spread out the values are.
Mean: Sum ÷ Count
Median: Middle value when sorted
Range: Maximum − Minimum
When should I use the median instead of the mean?
When a few unusually large or small numbers would give a false picture. Incomes and house prices are good examples — a few very high values pull the mean up, while the median stays closer to the typical case.
What is the difference between average and mean?
In everyday use, they mean the same thing. Strictly speaking, average is a general word for any measure of the centre. The mean is one specific type — the median and mode are also kinds of average.
