This outline of statistics as an aid in decision making will introduce a reader with limited mathematical background to the most important modern statistical methods. This is a revised and enlarged version, with major extensions and additions, of my "Angewandte Statistik" (5th ed.), which has proved useful for research workers and for consulting statisticians. Applied statistics is at the same time a collection of applicable statistical methods and the application of these methods to measured and/or counted observations. Abstract mathematical concepts and derivations are avoided. Special emphasis is placed on the basic principles of statistical formulation, and on the explanation of the conditions under which a certain formula or a certain test is valid. Preference is given to consideration of the analysis of small sized samples and of distribution-free methods. As a text and reference this book is written for non-mathematicians, in particular for technicians, engineers, executives, students, physicians as well as researchers in other disciplines. It gives any mathematician interested in the practical uses of statistics a general account of the subject. Practical application is the main theme; thus an essential part of the book consists in the 440 fully worked-out numerical examples, some of which are very simple; the 57 exercises with solutions; a number of different compu tational aids; and an extensive bibliography and a very detailed index. In particular, a collection of 232 mathematical and mathematical-statistical tables serves to enable and to simplify the computations.
The Fragrant Mind is written in an easy, accessible style for anyone who wishes to learn how essential oils can influence our minds and emotions and how to use aromatherapy to maintain a peaceful equilibrium or bring about positive change. Valerie Worwood's The Complete Book of Essential Oils and Aromatherapy (over 200,000 copies sold) has become the encyclopedia of essential oils and aromatherapy, earning itself the status of a popular household and reference classic. In this companion volume, Worwood concentrates on the emotional, psychological, and mood-changing effects of nature's oils.
Statistics, 2nd Edition teaches statistics with a modern, data-analytic approach that uses graphing calculators and statistical software. It allows more emphasis to be put on statistical concepts and data analysis rather than following recipes for calculations. This gives readers a more realistic understanding of both the theoretical and practical applications of statistics, giving them the ability to master the subject.
Now in its third edition, Economics: The Basics continues to provide an engaging and topical introduction to the key issues in contemporary economics. Fully updated to take into account the global recession, ongoing problems in Eurozone economies, changing patterns in world trade, housing and currency markets, it covers fundamental issues, including: • How different economic systems function • The boom and bust cycle of market economies • The impact of emerging markets • How price, supply and demand interact • The role of the banking and finance industry • Whether we can emerge from recession and reduce poverty • The impact of economics on the environment With a glossary of terms, suggestions for further reading and new case studies covering subjects such as the choices facing developing economies, the impact of growth on the price of natural resources and the aftermath of the financial crash; this comprehensive and accessible guide is essential reading for anyone who wants to understand how economics works.
Apparitions of the Self is a groundbreaking investigation into what is known in Tibet as "secret autobiography", an exceptional, rarely studied literary genre that presents a personal exploration of intimate religious experiences. In this volume, Janet Gyatso translates and studies the outstanding pair of secret autobiographies by the famed Tibetan Buddhist visionary, Jigme Lingpa (1730-1798). Gyatso s translation marks the first time that works of this sort have appeared in a Western language. It is only one of the many virtues of Janet Gyatso s Apparitions of the Self that it gives us, at last, a full portrait of a Buddhist saint in all his self-admitted complexity and ambiguity...Lucid and literate...Significant points to ponder and subtle arguments to which to respond. This exceptional volume combines concise and felicitous translation with clear commentary and insightful analysis....What lends considerable interest to this work is the comparison Gyatso....makes between Tibetan literature and Western literary theory... (Apparitions of the Self) serves as a model of innovative scholarship.
Statistics in Plain English is a straightforward, conversational introduction to statistics that delivers exactly what its title promises. Each chapter begins with a brief overview of a statistic (or set of statistics) that describes what the statistic does and when to use it, followed by a detailed step-by-step explanation of how the statistic works and exactly what information it provides. Chapters also include an example of the statistic (or statistics) used in real-world research, "Worked Examples," "Writing It Up" sections that demonstrate how to write about each statistic, "Wrapping Up and Looking Forward" sections, and practice work problems. Thoroughly updated throughout, this edition features several key additions and changes. First, a new chapter on person-centered analyses, including cluster analysis and latent class analysis (LCA) has been added, providing an important alternative to the more commonly used variable-centered analyses (e.g., t tests, ANOVA, regression). Next, the chapter on non-parametric statistics has been enhanced with in-depth descriptions of Mann-Whitney U, Kruskal-Wallis, and Wilcoxon Signed-Rank analyses, in addition to the detailed discussion of the Chi-square statistic found in the previous edition. These nonparametric statistics are widely used when dealing with nonnormally distributed data. This edition also includes more information about the assumptions of various statistics, including a detailed explanation of the assumptions and consequences of violating the assumptions of regression, as well as more coverage of the normal distribution in statistics. Finally, the book features a multitude of real-world examples throughout to aid student understanding and provides them with a solid understanding of how several statistics techniques commonly used by researchers in the social sciences work. Statistics in Plain English is suitable for a wide range of readers, including students taking their first statistics course, professionals who want to refresh their statistical memory, and undergraduate or graduate students who need a concise companion to a more complicated text used in their class. The text works as a standalone or as a supplement and covers a range of statistical concepts from descriptive statistics to factor analysis and person-centered analyses.
