Conclusions, decisions, and actions that are data driven predominate in today?s world. Statistics-the subject of data analysis and data-based reasoning-is necessarily playing a vital role in virtually all professions. Some familiarity with this subject is now an essential component of any college education. Yet, pressures to accommodate a growing list of academic requirements often necessitate that this exposure be brief. Keeping these conditions in mind, we have written this book to provide students with a first exposure to the powerful ideas of modern statistics. It presents the key statistical concepts and the most commonly applied methods of statistical analysis. Moreover, to keep it accessible to freshman and sophomores from a wide range of disciplines, we have avoided mathematical derivations. They usually pose a stumbling block to learning the essentials in a short period of time. This book is intended for students who do not have a strong background in mathematics but seek to learn the basic ideas of statistics and their applications in a variety of practical settings. The core material of this book is common to almost all first courses in statistics and is designed to be covered well within a one-semester course in introductory statistics for freshman-seniors. It is supplemented with some additional special-topics chapters. "Provided by the Publisher".
