Introductory Statistics (PIE)

• New Case Studies: More than one-third of the chapter opener case studies are new and updated.
• New and Updated Exercises: Neil Weiss has updated exercises (and relevant data sets) where appropriate and has provided many new exercises in this edition.
• Procedure Boxes: Why, When, and How: The procedure boxes have been enhanced to include the "why, when, and how" of the methods. Each procedure box has a brief identifying title followed by a statement of its purpose (why it's used), the assumptions for its use (when it's used), and the steps for applying the procedure (how it's used).
• Parallel Procedures for Hypothesis Testing: Both the critical-value and P-value approaches to hypothesis testing appear in a single split-format procedure box, for ease of use and for facilitating the comparison of the two approaches.
• What Does It Mean: This feature is used, to state in "plain English" the meaning of definitions, formulas, and key facts. It's also used to summarize certain types of discussions.
• Interpretation Feature: This feature is used exclusively to interpret the results of statistical analyses.
• Parallel Presentations of Technology: The Weiss approach offers complete flexibility in the coverage of technology which includes options for use of MINITAB, Excel, and the TI-83 and TI-84 Plus. One or more technologies can be explored and compared. Instructions and output for each package are included in Technology Centers throughout the book.
• Option for Brief Probability Coverage: Because of Weiss's unique presentation, only a basic coverage of probability is required. Weiss's flexibility allows instructors the option to cover as much or as little probability as they would like. Introductory Statistics has two optional probability chapters though only a few sections are required to understand subsequent material.
• Option for Brief Sampling Coverage: In the new editions, the only sampling design required for study is simple random sampling. Further sampling designs (systematic random sampling, stratified sampling, cluster sampling, and multistage sampling) are available for coverage at the instructor's discretion.
• Option for Brief Experimental Design Coverage: In the new edition, coverage of experimental designs is optional. Introductions to the principles of experimental design, terminology of experimental design, and basic statistical designs are available for coverage at the instructor's discretion.
