Data is a branch of Mathematics which is used often and often used wrongly! The old phrase "lies, damned lies and statistics" is definitely relevant here. Information collected through surveys, product testing and experiments can be presented in a variety of ways to show pretty much anything the mathematician wants it to. In this unit I'll show you a few of the different ways of representing data as well as how to calculate probabilities for simple events. If you've made it this far I'm sure you'll do fine in these topics!
