Margins of Error: A Study of Reliability in Survey MeasurementEnhance 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:
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. |

For example, concepts like religiosity, depression, intelligence, social status, attitudes, psychological Well being, functional status, and personality may be difficult to measure precisely because they largely reflect unobserved ...
... empirical data are made with respect to more abstract concepts and theories, not simply observable variables. Measurement, thus, requires the clear specification of relations between theoretic constructs and observable indicators.
It is important in this context not to confuse the indicators of concepts with the theoretical constructs they are thought to reflect. To do so loses sight of the purpose of measurement. In principle, it is the theoretical constructs ...
On a practical level, once concepts and indicators are defined and agreed on, measurement is possible only if we can assume some type of equivalence across units of observation, e.g., respondents or households. As Abraham Kaplan (1964) ...
