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.
This book—Familie Allwein: Volume III: Western Migrations—is volume three of a series of books about the history of the Allwein family in America, a family descended from an eighteenth-century German immigrant Johannes (Hans) Jacob Allwein and his wife, Catharina. Familie Allwein: Volume III: Western Migrations builds upon earlier volumes of Familie Allwein, which dealt with the Allwein family’s emigration from Germany to America and their settlement in colonial Pennsylvania. The first volume, Familie Allwein—An Early History, set the stage for later volumes. The second volume, Familie Allwein—Journeys in Time and Place, covered Allwein descendants living east of the Allegheny Mountains over the seventy-year period from about 1870 through 1940. Part 1 of Journeys in Time and Place focuses on those families that settled in southeastern Pennsylvania, particularly in Lebanon, Philadelphia, and the Berks Counties. Part 2 of Journeys in Time and Place focuses on those families living in Dauphin, Lancaster, Adams, York, and Blair Counties in south central Pennsylvania. This third volume of Familie Allwein—Western Migrations—covers families who moved to western Pennsylvania and those who migrated farther west. Not only is the present volume an update on the families covered in earlier volumes of Familie Allwein but it also extends the coverage of Allwein families by tracing their paths west—not only to the western counties of Pennsylvania but also to Ohio, Indiana, Michigan, Iowa, Minnesota, Kansas, Nebraska, and places farther west, including California. As in earlier volumes of this series, the author’s careful documentation of all sources and attention to detail make it possible to reproduce his findings and re-examine his conclusions.
A handsome work of cartography. The maps match census data to the results of electron returns. The third study of the political attitudes of a group of women who attended Bennington College in the 1930s and 1940s. The first two (1943 and 1967) focused on the importance of the social environment in shaping and maintaining attitudes. The third, based on interviews conducted in 1984, investigates the effect not only of social factors, but also of the aging process and the changing times. Paper edition (unseen), $21.95.
