I have very little background in biostats, and need to learn it for medical research and research design.This book is difficult to read, has far too much emphasis on mathematics and far too little empahisis on concept. After a whole quarter in Biostats using this book, I can tell you very little about how and when to employ certain basis statistics tests or interpret them with confidence. The answers in the back are ofter erroneous, as is some of the text (according to my professor).The only thing I can seay that is good about this test is that the NCSS software that comes with it I think may be helpful at some point.I am back in the market for a better book!
