Este libro esta dirigido a investigadores, profesionales y estudiantes de posgrado (Ma ster y Doctorado) que buscan una gui a para realizar ana lisis psicome tricos de diferentes instrumentos de evaluacio n. Asumimos un nivel ba sico de conocimientos estadi sticos, pero estos conceptos se ira n repasando a lo largo de los diferentes capi tulos. Nos imaginamos que este texto (a) esperara pacientemente en algunos despachos implorando ser entregado, como recurso, a un estudiante, (b) tendra un lugar fijo en las mesas de los despachos donde continuamente, y debido a su uso diario, sera el primero del monto n, (c) estara en las mochilas de los estudiantes de postgrado, y los acompan ara felizmente desde casa al trabajo o a las clases y vuelta, (d) aparecera orgullosamente como un texto de referencia en los programas y guia s de estudio, y finalmente (e) como ocasional posavasos mientras se reflexiona profundamente acerca de co mo resolver los problemas de medida.

The goal of the book is to provide readers with the tools necessary for assessing the psychometric qualities of educational and psychological measures as well as surveys and questionnaires. Each chapter will cover an issue pertinent to psychometric and measurement practice, with an emphasis on application. Topics will be briefly discussed from a theoretical/technical perspective in order to provide the reader with the background necessary to correctly use and interpret the statistical analyses that will be presented subsequently.
The anticipated audience for this book includes researchers, practitioners, and graduate students searching for a guide to perform common psychometric analyses on various assessments, as discussed in many psychometric texts. We envision that this text will (a) patiently wait on some office shelves begging to be handed to a student as a resource, (b) have a permanent home on desks where it continually rises to the top of the stacks for daily use of the applied researcher, (c) be happily carried in bags to and from work and class by the graduate student learning techniques, (d) be listed proudly as a reference text on syllabi, and finally (e) as an occasional drink coaster while deep thoughts are pondered about how to solve measurement problems. We hope that through such uses, particularly the latter, that we have provided some insight and assistance to the user in appropriately applying the techniques and concepts discussed.
