Description For introductory undergraduate or graduate courses in statistics aimed at life science majors. Bringing Statistics to Life The Fifth Edition of Statistics for the Life Sciencesuses authentic examples and exercises from a wide variety of life science domains to give statistical concepts personal relevance, enabling students to connect concepts with situations they will encounter outside the classroom. The emphasis on understanding ideas rather than memorizing formulas makes the text ideal for students studying a variety of scientific fields: animal science, agronomy, biology, forestry, health, medicine, nutrition, pharmacy, physical education, zoology and more. In the fifth edition, randomization tests have been moved to the fore to motivate the inference procedures introduced in the text. There are no prerequisites for the text except elementary algebra.

Content and Approach. Real data in the examples and exercises provide practical and relevant ways for students to connect concepts to situations they will encounter outside the classroom.
Probability theory is included only to support statistics concepts. Students are taught to recognize the importance of an analysis that is appropriate for the research question to be answered, for the statistical design of the study, and for the nature of the underlying distributions. Students are led to recognize the impact on real research of design concepts such as random sampling, randomization, efficiency, and the control of extraneous variation by blocking or adjustment. The text concludes with a summary of all of the inference methods presented in the book and provides exercises that require students to apply all of what they have learned. Randomization methods have been added at the beginnings of Chapters 7, 8, 10, 11, and 12 to introduce or motivate most inference procedures in the text. Structured to Foster Success. Exercises are designed to focus students’ attention on concepts and interpretations rather than on computation.
While statistical software is not required to use this text, there are ample opportunities for students to implement the statistical methods learned using any statistical software package of their choosing. Electronic data files are provided for most examples and exercises. Unit Highlights provide a chance for students to connect ideas across multiple chapters. They include reflections, summaries, additional examples, and exercises. Updated and new exercises appear throughout the book, and many exercises from the previous edition that involved calculation and reading tables have been updated to require interpretation of computer output. Updated examples reflect current research from a variety life science disciplines, replacing many older examples in the previous edition. Unit Highlights were added to provide a necessary opportunity for students to connect ideas across multiple chapters.
They include reflections, summaries, additional examples, and exercises. Material on randomization-based inference has been added to introduce or motivate most inference procedures presented in this text. There is now a presentation of randomization methods at the beginnings of Chapters 7, 8, 10, 11, and 12. Table of Contents UNIT I: DATA AND DISTRIBUTIONS 1.
