The Analysis of Biological Data Third Edition by Michael C. Whitlock Dolph Schluter

The Analysis of Biological Data is a new approach to teaching introductory statistics to biology students. 
Whitlock and Schluter use several techniques to reach this unique audience. Throughout, they teach statistics 
in the context of interesting biological and medical examples; they emphasize intuitive understanding rather 
than an over-reliance on formulas; they focus on the data rather than the mathematical foundations of statistics; 
and they introduce - on a conceptual level - modern topics such as likelihood, regression, randomization, 
meta-analysis and the bootstrap. Instructors and students consistently praise the book's clear and engaging writing, 
strong visualization techniques, and the wide variety of fascinating and relevant biological examples.
