This is a good teaching manual on counting (combinatorial counting *e.g. how many was to choose 2 scoops of ice cream from 12 different flavors*). Counting in statistics is important, and for some reason isn't stressed in classes as much as it should. This text is good for teachers teaching advanced 6th graders or middle-school aged children. If you're clueless on counting, this book is for you. If you know how to count, then you can get by without this book.
