This Book is too good in terms of content as well as in the way of presentation. Also written in a very simple language. As I am a medical professional, I would like to recommend this book to all medical students.
This is by far the best book on Biostatistics that I have come across. Almost all of the fundamental and important topics of Biostatistics are explained in a very simple language and most importantly the book covers a step by step guide to perform data analysis in R, which I have rarely seen in any statistics book! I highly recommend this book to students and professionals.
