 This book presents the more subjective side of statistics-the art of data analytics. Each chapter explores a different question using fun, common sense examples that illustrate the concepts, methods, and applications of statistical techniques. Without going into the specifics of theorems, propositions, or formulas, it demonstrates statistics as a useful problem-solving tool. It features: examples throughout aimed to strengthen readers' understanding of statistical concepts and methods; a step-by-step approach to elementary statistical topics such as sampling, hypothesis tests, outlier detection, normality tests, robust statistics, and multiple regression; case studies that illustrate the use of the presented techniques; highlights of well-known shortcomings that can lead to false conclusions; and an introduction to advanced techniques such as validation and bootstrapping. --   Edited summary from book.
