From the book — Chapter 7. Four ways to describe a list of numbers. Mean is the total divided by how many — it's what people usually call "the average". Median is the middle value once the list is in order (for an even-count list, the mean of the two middles). Mode is whichever value appears most often. Range is the largest minus the smallest — a quick read on how spread out the numbers are.

Separators can be commas, spaces, tabs, semicolons, or new lines. Everything stays in your browser.
