Understandable Statistics: Concepts and Methods (AP Edition®)

Up-to-date technology-related examples include instruction appropriate for the latest versions of MINITAB®, SPSS®, and Excel®.

The "Foreshadowing" feature alerts students to additional related material to be presented in subsequent "Expand Your Knowledge" problems.

The "Looking Ahead" feature gives students a taste of forthcoming topics--showing them how the concepts and skills they're reading about will be useful in helping them grasp material covered later.

Problems featuring basic computation and using small data sets give students the chance to appreciate the formulas and mathematical processes that their calculators accomplish for them--and help them to better understand what the end result means.

Examples, guided exercises, and problem sets throughout the text feature interpretation. They also address the suitability of using a specified statistical method or process for analysis.

The "Critical Thinking" feature provides additional clarification on specific concepts, such as what tests are appropriate for what situations, what assumptions need to be made, what biases may affect the results, and when conclusions are justified..

"Critical Thinking" exercises and chapter review problems test students' understanding of statistical methods and their ability to interpret their results.

"Statistical Literacy Problems" in every section and problem set test understanding of terminology, statistical methods, and the appropriate conditions for use of the different processes. "Writing Projects" test both statistical literacy and critical thinking by asking students to express their understanding in words.

REVISED "Tech Notes!" provide best practices and accompanying screenshots to assist students who are using these programs.

REVISED "Using Technology" features further technology instruction at the end of each chapter in the Using Technology section.

REVISED real-world applications throughout the text include new examples from a variety of disciplines.

REVISED Examples and New Section Problems the emphasize critical thinking and interpretation of statistical results.

NEW Additional flexibility provided by dividing chapters into parts - brief introduction, brief summary, and end-of-chapter problems that are applicable to the sections in each part.

NEW Expanded emphasis on critical thinking, interpretation, and statistical literacy.

NEW Introduction of hypothesis testing using P-values.

NEW use of student's t distribution in confidence intervals and testing of means.

NEW Confidence intervals and hypothesis tests of difference of means.
