Available in PDF, EPUB and Kindle. Book excerpt: To the uninformed, surveys appear to be an easy type of research to design and conduct, but when students and professionals delve deeper, they encounter the vast complexities that the range and practice of survey methods present. To complicate matters, technology has rapidly affected the way surveys can be conducted; today, surveys are conducted via cell phone, the Internet, email, interactive voice response, and other technology-based modes. Thus, students, researchers, and professionals need both a comprehensive understanding of these complexities and a revised set of tools to meet the challenges. In conjunction with top survey researchers around the world and with Nielsen Media Research serving as the corporate sponsor, the Encyclopedia of Survey Research Methods presents state-of-the-art information and methodological examples from the field of survey research. Although there are other "how-to" guides and references texts on survey research, none is as comprehensive as this Encyclopedia, and none presents the material in such a focused and approachable manner. With more than 600 entries, this resource uses a Total Survey Error perspective that considers all aspects of possible survey error from a cost-benefit standpoint. Key Features Covers all major facets of survey research methodology, from selecting the sample design and the sampling frame, designing and pretesting the questionnaire, data collection, and data coding, to the thorny issues surrounding diminishing response rates, confidentiality, privacy, informed consent and other ethical issues, data weighting, and data analyses Presents a Reader′s Guide to organize entries around themes or specific topics and easily guide users to areas of interest Offers cross-referenced terms, a brief listing of Further Readings, and stable Web site URLs following most entries The Encyclopedia of Survey Research Methods is specifically written to appeal to beginning, intermediate, and advanced students, practitioners, researchers, consultants, and consumers of survey-based information.

Book Synopsis Survey Weights by : Richard Valliant
Download or read book Survey Weights written by Richard Valliant and published by . This book was released on 2018 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Survey Weights: A Step-by-Step Guide to Calculation is the first guide geared toward Stata users that systematically covers the major steps taken in creating survey weights. These weights are used to project a sample to some larger population and can be computed for either probability or nonprobability samples. Sample designs can range from simple, single-stage samples to more complex, multistage samples, each of which may use specialized steps in weighting to account for selection probabilities, nonresponse, inaccurate coverage of a population by a sample, and auxiliary data to improve precision and compensate for coverage errors. The authors provide many examples with Stata code.

This book was released on 1986 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: A historical prospective study was designed to assess the man weight status of subjects who participated in a behavioral weight reduction program in 1983 and to determine whether there was an association between the dependent variable weight change and any of 31 independent variables after a 2 year follow-up period. Data was obtained by abstracting the subjects records and from a follow-up questionnaire administered 2 years following program participation. Five hundred nine subjects (386 females and 123 males) of 1460 subjects who participated in the program, completed and returned the questionnaire. Results showed that mean weight was significantly different (p

Book Synopsis Weighing the Options by : Committee to Develop Criteria for Evaluating the Outcomes of Approaches to Prevent and Treat Obesity
Download or read book Weighing the Options written by Committee to Develop Criteria for Evaluating the Outcomes of Approaches to Prevent and Treat Obesity and published by National Academies Press. This book was released on 1995-03-15 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly one out of every three adults in America is obese and tens of millions of people in the United States are dieting at any one time. This has resulted in a weight-loss industry worth billions of dollars a year and growing. What are the long-term results of weight-loss programs? How can people sort through the many programs available and select one that is right for them? Weighing the Options strives to answer these questions. Despite widespread public concern about weight, few studies have examined the long-term results of weight-loss programs. One reason that evaluating obesity management is difficult is that no other treatment depends so much on an individual's own initiative and state of mind. Now, a distinguished group of experts assembled by the Institute of Medicine addresses this compelling issue. Weighing the Options presents criteria for evaluating treatment programs for obesity and explores what these criteria mean--to health care providers, program designers, researchers, and even overweight people seeking help. In presenting its criteria the authors offer a wealth of information about weight loss: how obesity is on the rise, what types of weight-loss programs are available, how to define obesity, how well we maintain weight loss, and what approaches and practices appear to be most successful. Information about weight-loss programs--their clients, staff qualifications, services, and success rates--necessary to make wise program choices is discussed in detail. The book examines how client demographics and characteristics--including health status, knowledge of weight-loss issues, and attitude toward weight and body image--affect which programs clients choose, how successful they are likely to be with their choices, and what this means for outcome measurement. Short- and long-term safety consequences of weight loss are discussed as well as clinical assessment of individual patients. The authors document the health risks of being overweight, summarizing data indicating that even a small weight loss reduces the risk of disease and depression and increases self-esteem. At the same time, weight loss has been associated with some poor outcomes, and the book discusses the implications for program evaluation. Prevention can be even more important than treatment. In Weighing the Options, programs for population groups, efforts targeted to specific groups at high risk for obesity, and prevention of further weight gain in obese individuals get special attention. This book provides detailed guidance on how the weight-loss industry can improve its programs to help people be more successful at long-term weight loss. And it provides consumers with tips on selecting a program that will improve their chances of permanently losing excess weight.
Book Synopsis Exploring some uses for instrumental-variable calibration weighting by : Phillip S. Kott
Download or read book Exploring some uses for instrumental-variable calibration weighting written by Phillip S. Kott and published by RTI Press. This book was released on 2013-01-01 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The WTADJX procedure incorporated into the 2012 release of SUDAAN 11® does instrumental-variable calibration weighting using a flexible nonlinear weight-adjustment function. We review the theory behind this procedure and discuss two potential uses. The first tends to reduce mean squared errors in the absence of unit nonresponse or coverage errors. The second adjusts for unit nonresponse when the variables governing the response mechanism differ from the variables used to calibrate the weights. This occurs either because the survey variables of interest cannot be roughly modeled as a linear function of the response-model variables or because the values of the response-model variables are known only for the respondents.

Book Synopsis Practical Tools for Designing and Weighting Survey Samples by : Richard Valliant
Download or read book Practical Tools for Designing and Weighting Survey Samples written by Richard Valliant and published by Springer Science & Business Media. This book was released on 2013-05-16 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: Survey sampling is fundamentally an applied field. The goal in this book is to put an array of tools at the fingertips of practitioners by explaining approaches long used by survey statisticians, illustrating how existing software can be used to solve survey problems, and developing some specialized software where needed. This book serves at least three audiences: (1) Students seeking a more in-depth understanding of applied sampling either through a second semester-long course or by way of a supplementary reference; (2) Survey statisticians searching for practical guidance on how to apply concepts learned in theoretical or applied sampling courses; and (3) Social scientists and other survey practitioners who desire insight into the statistical thinking and steps taken to design, select, and weight random survey samples. Several survey data sets are used to illustrate how to design samples, to make estimates from complex surveys for use in optimizing the sample allocation, and to calculate weights. Realistic survey projects are used to demonstrate the challenges and provide a context for the solutions. The book covers several topics that either are not included or are dealt with in a limited way in other texts. These areas include: sample size computations for multistage designs; power calculations related to surveys; mathematical programming for sample allocation in a multi-criteria optimization setting; nuts and bolts of area probability sampling; multiphase designs; quality control of survey operations; and statistical software for survey sampling and estimation. An associated R package, PracTools, contains a number of specialized functions for sample size and other calculations. The data sets used in the book are also available in PracTools, so that the reader may replicate the examples or perform further analyses.

Book excerpt: The American Community Survey (ACS) is a major new initiative from the U.S. Census Bureau designed to provide continuously updated information on the numbers and characteristics of the nation's people and housing. It replaces the "long form" of the decennial census. Using the American Community Survey covers the basics of how the ACS design and operations differ from the long-form sample; using the ACS for such applications as formula allocation of federal and state funds, transportation planning, and public information; and challenges in working with ACS estimates that cover periods of 12, 36, or 60 months depending on the population size of an area. This book also recommends priority areas for continued research and development by the U.S. Census Bureau to guide the evolution of the ACS, and provides detailed, comprehensive analysis and guidance for users in federal, state, and local government agencies, academia, and media.
Book Synopsis Weight Management by : Institute of Medicine
Download or read book Weight Management written by Institute of Medicine and published by National Academies Press. This book was released on 2003-12-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.
