The Secrets Series® is breaking new ground again. A two-color page layout, a portable size, and a list of the "Top 100 Secrets” in biostatistics and epidemiology help readers to better meet the challenges they face today. And, at no extra charge, purchasers also receive online access to the complete contents of the text via Elsevier's innovative STUDENT CONSULT website. Readers will still find all of the features they rely on the Secret Series® for-a question-and-answer format, lists, mnemonics, and tables and an informal tone that make reference fast and easy. No matter what questions arise in practice or while preparing for boards, this new volume has the answers-in print and online.
