xii Preface Hallmark Features Great care has been taken to ensure that each chapter of Elementary Statistics will help students understand the concepts presented. The following features are designed to help meet that objective of conceptual understanding. Real Data Thousands of hours have been devoted to finding data that are real, meaningful, and interesting to students. 94% of the examples are based on real data, and 93% of the exercises are based on real data. Some exercises refer to the 46 data sets listed in Appendix B, and 20 of those data sets are new to this edition. Exercises requiring use of the Appendix B data sets are located toward the end of each exercise set and are marked with a special data set icon . These data sets are also available in MyMathLab for School, including data sets for StatCrunch. Appendix B includes descriptions of the 46 data sets that can be downloaded from www.TriolaStats.com in formats for Excel™, Minitab™, JMP, SPSS, and TI-83>84™ Plus calculators. (Because TI-83>84 Plus calculators have limited memory, several larger data sets have been truncated for TI users, and answers have been annotated when appropriate.) Readability Great care, enthusiasm, and passion have been devoted to creating a book that is readable, understandable, interesting, and relevant. Students pursuing any field of study are sure to find applications related to their future work.
