"The book is divided into three Parts: Part One has chapters that introduce data analysis and SPSS; Part Two contains eight chapters on descriptive statistics that begin with frequency tables and go through multiple regression; and Part Three includes six chapters on inferential statistics. Part One: Getting Started begins by answering some questions most students have right at the start © questions like why study data analysis and how much math and computer knowledge is required? Essential concepts from research methods relevant for data analysis are also explained. Part Two: Descriptive Statistics: Answering Questions about Your Data demonstrates procedures to use when the analyst is only concerned with describing the cases for which he or she actually has data. Statistics summarizing single variables (univariate statistics) are presented first and then statistics summarizing relationships between variables (multivariate statistics). Frequency tables, measures of central tendency, measures of dispersion, crosstabs, measures of association, subgroup means, and regression are all covered as are bar charts, pie charts, histograms, and clustered bar charts. Part Three: Inferential Statistics: Answering Questions about Populations explains procedures which allow the analyst to draw conclusions about the population from which his or her sample of cases was randomly selected. It begins with a simple chapter on the statistical theory behind inferential statistics. A four-step approach to hypothesis testing is introduced in the next chapter and demonstrated with one-sample t test hypotheses. The remaining chapters present different types of hypothesis tests including paired-samples, independent-samples, one and two-way ANOVA, and chi-square"--Provided by publisher.

The Science of Answering Questions: A Statistical Approach introduces students to the process of determining an answer to a question or problem through the collection of information, the use of statistical tools on the information, and reaching a conclusion based on the results. Opening chapters explore the evidence needed to answer the question of interest. Students learn about variables, levels of measurement, populations, samples, and sampling, as well as commonly used and freely available statistical software that can be used in statistical analyses. Additional chapters introduce ways to display and describe information collected from the sample, including summaries, summary tables, and graphs. Descriptive statistics and inferential statistics are covered. Readers explore descriptors, predictors, point estimation, deviation and variance, probability distributions, and interval estimation. Chapters in the latter half of the text focus on answering different questions of interest or the same question with different types of collected information. These chapters cover hypothesis testing, one sample proportion, multinomial, pre-post, homogeneity, correlation, independence, and more. Appendices provide students with helpful references related to critical values and standard normal probabilities. Providing students with a complete yet accessible introduction, The Science of Answering Questions is an excellent introductory resource for a course in statistics.

It is perfect for instructors, students, and practitioners as a supplement to more comprehensive materials, or as a desk reference with quick answers to the most frequently asked questions. “The key strength of this book is the straightforward approach. I love the to-the-point question-and-answer format. . . . This book would be useful in both statistics and research methods courses . . . [and] in math tutoring labs. I love the tone the author uses, as it is not condescending. Students will be encouraged.” —Jamie Brown, Mercer University “The sequencing of the questions works very well—from the most basic to the more intimidating questions often asked by students in an intro class. . . . If Dr. Salkind is the author, I know it will be well-written, and both entertaining and easy to understand.” —Linda Martinez, California State University, Long Beach “Practical examples from all types of work: showing the steps to do each analysis and then the ways to use the results responsibly.” —Jennifer R.

Finally, an introductory statistics text that provides broad coverage, limited theory, clear explanations, plenty of practice opportunities, and examples that engage today's students! Using General Social Survey data from 1980 and 2010, Robert Szafran asks students to consider how young adults have changed over the last 30 years. Students learn to select an appropriate data analysis technique, carry out the analysis, and draw appropriate conclusions. Changes in subjective beliefs (such as freedom of speech and abortion) and objective characteristics (like years of schooling and marital status) are examined. In answering the question about how young adults have changed, students acquire a broad knowledge of basic statistics and extensive experience with SPSS.

Celebrating the life of an admired pioneer in statistics In this captivating and inspiring memoir, world-renowned statistician George E. P. Box offers a firsthand account of his life and statistical work. Writing in an engaging, charming style, Dr. Box reveals the unlikely events that led him to a career in statistics, beginning with his job as a chemist conducting experiments for the British army during World War II. At this turning point in his life and career, Dr. Box taught himself the statistical methods necessary to analyze his own findings when there were no statisticians available to check his work. Throughout his autobiography, Dr. Box expertly weaves a personal and professional narrative to illustrate the effects his work had on his life and vice-versa. Interwoven between his research with time series analysis, experimental design, and the quality movement, Dr. Box recounts coming to the United States, his family life, and stories of the people who mean the most to him. This fascinating account balances the influence of both personal and professional relationships to demonstrate the extraordinary life of one of the greatest and most influential statisticians of our time. An Accidental Statistician also features: • Two forewords written by Dr. Box’s former colleagues and closest confidants • Personal insights from more than a dozen statisticians on how Dr. Box has influenced and continues to touch their careers and lives • Numerous, previously unpublished photos from the author’s personal collection An Accidental Statistician is a compelling read for statisticians in education or industry, mathematicians, engineers, and anyone interested in the life story of an influential intellectual who altered the world of modern statistics.

Statistical Questions in Evidence-based Medicine is a companion volume to the new edition of An Introduction to Medical Statistics and includes questions and answers which are complementary to the textbook. This new book takes a practical approach that develops an understanding of statistics and suggests appropriate questions to ask about research methods, figures and conclusions and whether they are evidence based. The book is a model of clarity and common sense in what is frequently an unnecessarily obscure area of science. It looks at the application of and provides a critique of statistics, encouraging an evidence-based approached to medical statistics. Through the critical evaulation of the published medical literature, the text will enable both students and researchers to understand the appropriate use of descriptive and inferential statistics in study design and when writing papers. The reproduction of short excerpts of material from published papers or summaries of their results are included and they are considered in a question and answer format. The reader can either read through the series of cases and follow through worked examples or work through the book themselves as a series of exercises. The questions are clearly graded, through the use of icons, in terms of difficulty into standard and postgraduate levels. This book will prove invaluable to students, medical researchers and doctors alike.
