Acerca del contenido

Este texto se centra en problemas concretos de investigación, y cómo la utilización de un programa permite resolver adecuadamente el objeto central de la investigación (Description in English below). Esta obra desarrolla cuatro técnicas basadas en otros tantos ejemplos: Análisis Exploratorio, Factorial de Componentes, Factorial de Correspondencias y Conglomerados; precedidas de un capítulo sobre Análisis Exploratorio. Cada técnica se explica utilizando un caso real de investigación, se proporcionan otros dos casos prácticos, procedentes de investigaciones reales para que los lectores practiquen y lleguen a dominar cada una de las técnicas. Description in English: Three aspects differentiate this work from the large number of books currently published on data analysis programs: - The fundamental objective is not to explain a statistical application, but to use it as a "tool" to solve problems on research. - The minimum mathematical apparatus has been used, focusing the exposition on the criteria for using data analysis techniques, and on the interpretation of the results provided. - This text focuses on specific research problems, and how the use of a program allows to adequately solve the central objective of the investigation. In this work, four techniques are developed based on many other examples: - Exploratory Analysis, Factorial of Components, Factorial of Correspondences and Clusters; preceded by a chapter on Exploratory Analysis. - Each technique is explained using a real research case, and each chapter provides two other case studies, drawn from real research, for readers to practice and master each of the techniques.
