For graduate or undergraduate courses in biology, agronomy, medical and health sciences, nutrition, pharmacy, animal science, physical education, forestry, and other life sciences.

With a strong emphasis on real data, exploratory data analysis, interpretation of results, and checking assumptions, this text clearly conveys the key concepts of statistics as applied to life sciences while incorporating tools and themes of modern data analysis. The authors' goal is to help students understand concepts not memorize formulas; they make liberal use of exercises, worked examples, and graphical methods to do so.

**Features:**

- NEW-- New sections throughout--Including sections on probability rules, random variables, the Wilcoxon Signed-Rank Test, and two-way ANOVA and ANOVA for randomized blocks designs.
- Shows students tools for data analysis beyond standard introductory methods.
- NEW-- Expanded treatment of logistic regression--Appears in Chapter 12.
- Introduces students to a widely used modeling technique.
- NEW-- Approximately 100 new exercises added to the edition--Provides for a total of over 700 exercises in the text.
- Gives students ample opportunity to practice learned concepts.
- Use of real data.
- Provides practical and relevant examples to help students build connection from the concept to the problems.
- Use of graphical data and analysis.
- Facilitates for students an understanding of statistics and data.
- An interpretation of results in context.
- Presents statistics as relevant to students.
- "What to do When" section--Appears in Chapter 13.
- Provides students a summary of methods.
