Summary: Statistics professors increasingly want a more economical and streamlined text that covers only those topics that are included in their introductory statistics course. Essentials of Statistics, 2e is the book for these instructors.
Drawn from Triola's Elementary Statistics, 9e, Essentials has the same strong pedagogy, writing style, flow charts and margin essays.
Chap...show moreter-Opening Features: A list of chapter sections previews the chapter for the student; a chapter-opening problem using real data then motivates the chapter material; and the first section is a chapter overview that provides a statement of the chapter's objectives.
Margin Essays: The text includes 103 margin essays, which illustrate uses and abuses of statistics in real, practical, and interesting applications. Topics include "Do Boys or Girls Run in the Family?" "Accuracy of Vote Counts," "Test of Touch Therapy," and "Picking Lottery Numbers."
About 67% of exercises in Triola Essentials, 2e include real data.
Real Data Sets: These are used extensively throughout the book. Appendix B lists 30 data sets, 14 of which are new. These data sets are provided in printed form in Appendix B, and in electronic form on CD packaged with the book. The data sets include such varied topics as ages of Queen Mary stowaways, alcohol and tobacco use in animated children's movies, eruption of the Old Faithful geyser, diamond prices and characteristics, and movie financial and rating data.
Flowcharts: These appear throughout the text to simplify and clarify more complex concepts and procedures.
STATDISK, Minitab, Excel and TI-83/84 PLUS instructions and output appear throughout the book.
End-of-Chapter Features: A Chapter Review summarizes the key concepts and topics of the chapter; Review Exercises for practice on the chapter concepts and procedures; Cumulative Review Exercises reinforce earlier material; From Data to Decision: Critical Thinking, a capstone problem requires critical thinking and a writing component; Cooperative Group Activities encourage active learning in groups; Internet Projects involve students with Internet data sets and, in some cases, applets.
Interviews: Every chapter of the text includes author-conducted interviews with professional men and women in a variety of fields who use statistics in their day-to-day work.
Quick-Reference Endpapers: Tables A-2 and A-3 (the normal and r distributions) are reproduced on the front inside pages. A symbol table is included at the back of the book for quick and easy reference to key symbols.
Detachable Formula/Table Card: This insert, organized by chapter, gives students a quick reference for studying, or for use when taking tests (if allowed by the instructor.)
CD-ROM: prepared by Mario F. Triola and packaged with every new copy of the text, includes the data sets (except for Data Set 4) from Appendix B in the textbook. These data sets are stored as text files, Minitab worksheets, SPSS files, SAS files, Excel workbooks, and a TI-83/84 Plus application. The CD also includes programs for the TI-83/84 Plus® graphing calculator, STATDISK statistical software, and DDXL, an Excel add-in, which enhances the capabilities of Excel's statistical programs.
StatExplore: StatExplore is online statistical software offerin an easy-to-use interface and an alternative to commercial statistical software. StatExplore is available in the MyMathLab course.
New To This Edition
Greater emphasis on interpreting results. Instead of simply obtaining answers, the implications and consequences of answers are considered.
Exercises: over 1000 exercises, more than 58 percent of the exercises are new.
Procedures: In Chapters 6, 7, and 8, there is a change from "n30" to " known" as a key criterion for choosing between the normal and t distributions. This change reflects the common practice used by working professionals, it provides more accurate results, and it is better for students moving on to other statistics courses, yet it is not much more difficult than using the "n30" criterion.
