Most books on measurement present a statistical orientation or an orientation toward measurement theory. Although these approaches are valuable, Measurement Error and Research Design is 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. An author maintained website, http: //www.business.uiuc.edu/~madhuv/msmt.html features datasets and suggestions for using the book in courses.
