Query: Saved my butt...

I had a day to study for the final MS1 biostats exam. I had attended almost none of the classes, and had not taken stats in undergrad. I needed an overview that could explain the concepts of this tricky subject to me in a matter of hours.Well this book did just that. Unlike the large, complex biostats textbooks my friends picked up a few days before the test (and couldn't finish) it is very short, very readable, and emphasizes only the points you need to understand. It has a great symbol index as well as a good terminology index.This is the first High yield book I have purchased, and I have come away highly impressed.
