Book excerpt: Enhance the quality of survey results by recognizing and reducing measurement errors. Margins of Error: A Study of Reliability in Survey Measurement demonstrates how and hwy identifying the presence and extent of measurement errors in survey data is essential for improving the overall collection and analysis of the data. The author outlines the consequences of ignoring survey measurement errors and also discusses ways to detect and estimate the impact of these errors. This book also provides recommendations of improving the quality of survey data. Logically organized and clearly written, this book: Deconstructs the data gathering process into six main elements of the response process: question adequacy, comprehension, accessibility, retrieval, motivation, and communication Provides an exhaustive review of valuable reliability estimation techniques that can be applied to survey data Identifies the types of questions and interviewer practices that are essential to the collection of reliable data Addresses hypotheses regarding which survey questions, sources of information, and questionnaire formats produce the most reliable data In conjunction with research data gathered on nearly 500 survey measures and the application of an empirical approach grounded in classical measurement theory, this book discusses the sources of measurement error and provides the tools necessary for improving survey data collection methods. Margins of Error enables statisticians and researchers in the fields of public opinion and survey research to design studies that can detect, estimate, and reduce measurement errors that may have previously gone undetected. This book also serves as a supplemental textbook for both undergraduate and graduate survey methodology courses.

Available in PDF, EPUB and Kindle. Book excerpt: Statistics is confusing, even for smart, technically competent people. And many students and professionals find that existing books and web resources don’t give them an intuitive understanding of confusing statistical concepts. That is why this book is needed. Some of the unique qualities of this book are: • Easy to Understand: Uses unique “graphics that teach” such as concept flow diagrams, compare-and-contrast tables, and even cartoons to enhance “rememberability.” • Easy to Use: Alphabetically arranged, like a mini-encyclopedia, for easy lookup on the job, while studying, or during an open-book exam. • Wider Scope: Covers Statistics I and Statistics II and Six Sigma Black Belt, adding such topics as control charts and statistical process control, process capability analysis, and design of experiments. As a result, this book will be useful for business professionals and industrial engineers in addition to students and professionals in the social and physical sciences. In addition, each of the 60+ concepts is covered in one or more articles. The 75 articles in the book are usually 5–7 pages long, ensuring that things are presented in “bite-sized chunks.” The first page of each article typically lists five “Keys to Understanding” which tell the reader everything they need to know on one page. This book also contains an article on “Which Statistical Tool to Use to Solve Some Common Problems”, additional “Which to Use When” articles on Control Charts, Distributions, and Charts/Graphs/Plots, as well as articles explaining how different concepts work together (e.g., how Alpha, p, Critical Value, and Test Statistic interrelate). ANDREW A. JAWLIK received his B.S. in Mathematics and his M.S. in Mathematics and Computer Science from the University of Michigan. He held jobs with IBM in marketing, sales, finance, and information technology, as well as a position as Process Executive. In these jobs, he learned how to communicate difficult technical concepts in easy - to - understand terms. He completed Lean Six Sigma Black Belt coursework at the IASSC - accredited Pyzdek Institute. In order to understand the confusing statistics involved, he wrote explanations in his own words and graphics. Using this material, he passed the certification exam with a perfect score. Those statistical explanations then became the starting point for this book.

Book excerpt: To err is human. Yet most of us go through life assuming (and sometimes insisting) that we are right about nearly everything, from the origins of the universe to how to load the dishwasher. In Being Wrong, journalist Kathryn Schulz explores why we find it so gratifying to be right and so maddening to be mistaken. Drawing on thinkers as varied as Augustine, Darwin, Freud, Gertrude Stein, Alan Greenspan, and Groucho Marx, she shows that error is both a given and a gift—one that can transform our worldviews, our relationships, and ourselves.

Available in PDF, EPUB and Kindle. Book excerpt: Why the rise of redundant precision in architecture and the accompanying fear of error are key to understanding the discipline's needs, anxieties and desires. When architects draw even brick walls to six decimal places with software designed to cut lenses, it is clear that the logic that once organized relations between precision and material error in construction has unraveled. Precision, already a promiscuous term, seems now to have been uncoupled from its contract with truthfulness. Meanwhile error, and the always-political space of its dissent, has reconfigured itself. In The Architecture of Error Francesca Hughes argues that behind the architect's acute fetishization of redundant precision lies a special fear of physical error. What if we were to consider the pivotal cultural and technological transformations of modernism to have been driven not so much by the causes its narratives declare, she asks, as by an unspoken horror of loss of control over error, material life, and everything that matter stands for? Hughes traces the rising intolerance of material vagaries—from the removal of ornament to digitalized fabrication—that produced the blind rejection of organic materials, the proliferation of material testing, and the rhetorical obstacles that blighted cybernetics. Why is it, she asks, that the more we cornered physical error, the more we feared it? Hughes's analysis of redundant precision exposes an architecture of fear whose politics must be called into question. Proposing error as a new category for architectural thought, Hughes draws on other disciplines and practices that have interrogated precision and failure, citing the work of scientists Nancy Cartwright and Evelyn Fox Keller and visual artists Gordon Matta-Clark, Barbara Hepworth, Rachel Whiteread, and others. These non-architect practitioners, she argues, show that error need not be excluded and precision can be made accountable.

Available in PDF, EPUB and Kindle. Book excerpt: Basic Statistics with R: Reaching Decisions with Data provides an understanding of the processes at work in using data for results. Sections cover data collection and discuss exploratory analyses, including visual graphs, numerical summaries, and relationships between variables - basic probability, and statistical inference - including hypothesis testing and confidence intervals. All topics are taught using real-data drawn from various fields, including economics, biology, political science and sports. Using this wide variety of motivating examples allows students to directly connect and make statistics essential to their field of interest, rather than seeing it as a separate and ancillary knowledge area. In addition to introducing students to statistical topics using real data, the book provides a gentle introduction to coding, having the students use the statistical language and software R. Students learn to load data, calculate summary statistics, create graphs and do statistical inference using R with either Windows or Macintosh machines. - Features real-data to give students an engaging practice to connect with their areas of interest - Evolves from basic problems that can be worked by hand to the elementary use of opensource R software - Offers a direct, clear approach highlighted by useful visuals and examples

Available in PDF, EPUB and Kindle. Book excerpt: First Published in 1995. In the past decade or two, the most important theoretical perspective to emerge in mathematics education has been that of constructivism. This burst onto the international scene at the controversial Eleventh International Conference on the Psychology of Mathematics Education in Montreal in the summer of 1987. No one there will forget von Glasersfeld's authoritative plenary presentation on radical constructivism, and his replies to critics. Ironically, the conference, at which attacks on radical constructivism were perhaps intended to expose fatally its weaknesses, served as a platform from which the theory was launched to widespread international acceptance and approbation. Radical constructivism is a theory of knowing that provides a pragmatic approach to questions about reality, truth, language and human understanding. It breaks with the philosophical tradition and proposes a conception of knowledge that focuses on experiential fit rather than metaphysical truth. It claims to be a useful approach, not the revelation of a timeless world. The ten chapters of this book present different facets in an elegantly written and thoroughly argued account of this epistemological position, providing a profound analysis of its central concepts.

Book excerpt: From one of the foremost authorities on education in the United States, former U.S. assistant secretary of education, “whistle-blower extraordinaire” (The Wall Street Journal), author of the best-selling The Death and Life of the Great American School System (“Important and riveting”—Library Journal), The Language Police (“Impassioned . . . Fiercely argued . . . Every bit as alarming as it is illuminating”—The New York Times), and other notable books on education history and policy—an incisive, comprehensive look at today’s American school system that argues against those who claim it is broken and beyond repair; an impassioned but reasoned call to stop the privatization movement that is draining students and funding from our public schools. In Reign of Error, Diane Ravitch argues that the crisis in American education is not a crisis of academic achievement but a concerted effort to destroy public schools in this country. She makes clear that, contrary to the claims being made, public school test scores and graduation rates are the highest they’ve ever been, and dropout rates are at their lowest point. She argues that federal programs such as George W. Bush’s No Child Left Behind and Barack Obama’s Race to the Top set unreasonable targets for American students, punish schools, and result in teachers being fired if their students underperform, unfairly branding those educators as failures. She warns that major foundations, individual billionaires, and Wall Street hedge fund managers are encouraging the privatization of public education, some for idealistic reasons, others for profit. Many who work with equity funds are eyeing public education as an emerging market for investors. Reign of Error begins where The Death and Life of the Great American School System left off, providing a deeper argument against privatization and for public education, and in a chapter-by-chapter breakdown, putting forth a plan for what can be done to preserve and improve it. She makes clear what is right about U.S. education, how policy makers are failing to address the root causes of educational failure, and how we can fix it. For Ravitch, public school education is about knowledge, about learning, about developing character, and about creating citizens for our society. It’s about helping to inspire independent thinkers, not just honing job skills or preparing people for college. Public school education is essential to our democracy, and its aim, since the founding of this country, has been to educate citizens who will help carry democracy into the future.

Book excerpt: This book asks the question: what is the role of memory during a political transition? Drawing on Ethiopian history, transitional justice, and scholarly fields concerned with memory, museums and trauma, the author reveals a complex picture of global, transnational, national and local forces as they converge in the story of the creation and continued life of one modest museum in the Ethiopian capital, Addis Ababa—the Red Terror Martyrs Memorial Museum. It is a study from multiple margins: neither the case of Ethiopia nor memorialization is central to transitional justice discourse, and within Ethiopia, the history of the Red Terror is sidelined in contemporary politics. From these nested margins, traumatic memory emerges as an ambiguous social and political force. The contributions, meaning and limitations of memory emerge at the point of discrete interactions between memory advocates, survivor-docents and visitors. Memory from the margins is revealed as powerful for how it disrupts, not builds, new forms of community.
