Since a critical role of the survey industry is to provide input to world leaders for decision making, it is imperative that the data generated be of such 8 the evolution of survey process quality quality that they can serve as a basis for informed decisions The methods available to assure good quality should be known and accessible to all serious survey organizations Today, this is unfortunately not... dealing with the quality of data collected through the survey process Total survey error, as measured by the mean squared error and its component parts, is the primary criterion for assessing the quality of the survey data Chapter 1 traces the origins of survey research and introduces the concept of survey quality and data quality Chapter 2 provides a nontechnical discussion of how data quality is measured... significance, to mention just a few of the more common statistical methods In this book we treat the branch of statistics called survey methodology and, more specifically, survey quality To provide a framework for the book, we define both a survey and survey quality in this chapter We begin with the definition of a survey and in Section 1.2 describe some types of surveys typically encountered in practice today... every survey in official statistics should be accompanied by a quality declaration, and that some surveys or survey systems in the United States have produced quality profiles (see Chapter 8) A quality profile is a collection of all that is known about the quality of a survey or a system of surveys Such profiles have been developed for the Survey of Income and Program Participation, the Annual Housing Survey, ... dimensions of survey quality Another definition distinguishes between quality of design and quality of conformance (Juran and Gryna, 1980) An example of design quality is how 14 the evolution of survey process quality data are presented A publication with multicolored charts presenting statistical data may be aesthetically superior to monochromatic charts or simple tables Thus, design quality is said to be... throughout the book into lessons for practical survey design The book covers many concepts and ideas for understanding the nature of survey error, techniques for improving survey quality and, where possible, their cost implications, and methods for evaluating data quality in ongoing survey programs A major theme of the book is to introduce readers to the language or terminology of survey errors so that... practice today Our treatment of surveys concludes with a short history of the evolution of survey methodology in social–economic research (Section 1.3) The next three sections of this chapter deal with the very difficult to define concept of quality; in particular, survey quality We describe briefly what quality means in the context of survey work and how it has coevolved with surveys, especially in recent .
