How it works
Add up every number in the list, then divide by how many numbers there are. The list can be as long as you like, and the numbers can be whole or decimal.
One very large or very small number can pull the average far from most of the others. In that case the median can be a better picture of the typical value.
Worked example
Your list has 5 numbers, and their average is 21.
Questions
Do the numbers have to be separated by commas?
No. Spaces, new lines, commas and semicolons all work, so paste them in however they come.
What if one number is missing?
Leave it out of the list. A blank is not the same as a zero, and a zero would pull the average down.
Is the average the same as the median?
Not always. The average adds everything up, while the median is the middle number once the list is sorted. They match only when the numbers are spread evenly.
