Frequently asked questions

What is the difference between mean and median?
The mean is the sum divided by the count. The median is the middle value after sorting, so extreme values affect it less.
Can I use decimal and negative numbers?
Yes. Both decimal and negative values are supported.
How is the median calculated for an even number of values?
The two middle values are added together and divided by two.
