Most books on measurement present a statistical orientation or an orientation toward measurement theory. Although these approaches are valuable,Measurement Error and Research Designis motivated by the lack of literature that enhances understanding of measurement error, its sources, and its effects on responses. This book's purpose is to enhance the design of research, both of measures and of methods. Author Madhu Viswanathan's work is organized around the meaning of measurement error. It begins with a brief overview of measurement principles supplemented with many examples to provide necessary background to the reader. It analyzes the various causes of different types of measurement error, the nature of responses that would characterize each type of error, and the pattern of empirical outcomes that would be observed. This approach provides guidance in developing and editing items and measures and in designing methods before the fact. It is also perfect for using empirical results to redesign items, measures, and methods. Measurement is treated at a nuts-and-bolts level with concrete examples or errors and empirical procedures.
