PREFACE
Approach | Elementary Statistics:A Step by Step Approach was written as an aid in the beginning statistics course to students whose mathematical background is limited to basic algebra. The book follows a nontheoretical approach without formal proofs, explaining concepts intuitively and supporting them with abundant examples. The applications span a broad range of topics certain to appeal to the interests of students of diverse backgrounds, and they include problems in business, sports, health, architecture, education, entertainment, political science, psychology, history, criminal justice, the environment, transportation, physical sciences, demographics, eating habits, and travel and leisure. |
About This Book | While a number of important changes have been made in the eighth edition, the learning system remains untouched and provides students with a useful framework in which to learn and apply concepts. Some of the retained features include the following: |
Over 1200 exercises are located at the end of major sections within each chapter. Hypothesis-Testing Summaries are found at the end of (z, t, x2, and F tests for testing means, proportions, and variances) and (correlation, chi-square, and ANOVA) show students the different types of hypotheses and the types of tests to use. A Data Bank listing various attributes (educational level, cholesterol level, gender, etc.) for 100 people and several additional data sets using real data are included and referenced in various exercises and projects throughout the book. An updated reference card containing the formulas and the z, t, x2, and PPMC tables is included with this textbook. End-of-chapter Summaries, Important Terms, and Important Formulas give students a concise summary of the chapter topics and provide a good source for quiz or test preparation. Review Exercises are found at the end of each chapter. Special sections called Data Analysis require students to work with a data set to perform various statistical tests or procedures and then summarize the results. The data are included in the Data Bank in . Chapter Quizzes, found at the end of each chapter, include multiple-choice, true/false, and completion questions along with exercises to test students knowledge and comprehension of chapter content. The Appendices provide students with extensive reference tables, a glossary, and answers to all quiz questions and odd-numbered exercises. Additional Online Appendices include algebra review, an outline for report writing, Bayes theorem, and an alternative method for using the standard normal distribution. These can be found at www.mhhe.com/bluman. The Applying the Concepts feature is included in all sections and gives students an opportunity to think about the new concepts and apply them to examples and scenarios similar to those found in newspapers, magazines, and radio and television news programs.
