How it works
The mean is the sum of all the values divided by how many there are: mean = sum ÷ count. The median is the middle value once the numbers are sorted, or the average of the two middle values when the count is even. The range is the largest value minus the smallest.
Frequently asked questions
What is the difference between mean and median?
The mean is the arithmetic average of all values. The median is the middle value when sorted, which is less affected by very large or very small outliers.
How should I separate the numbers?
Any mix of commas, spaces or new lines works. The calculator reads every number it finds in the box.
Can I include negative numbers and decimals?
Yes. Negative values and decimals are both supported.
