El conocimiento estadístico se ha de basar en la realidad, en lo que es observable, para poder elaborar conclusiones acerca de los fenómenos aleatorios. La teoría que desarrolla los procesos de evaluación de las conclusiones y que facilita el método de validación de las mismas es la inferencia estadística. Esta teoría acoge necesariamente el cálculo de probabilidades, tanto para disponer de modelos que permitan explicar los fenómenos analizados como para medir la aleatoriedad de la información utilizada y de las propias conclusiones alcanzadas. El modelo de sistematización, análisis y síntesis de la información disponible es la estadística descriptiva. Esta obra recoge, de manera sistematizada y pedagógica, una selección de problemas que ayudan al estudiante a comprender y asimilar los conceptos relativos a la estadística descriptiva y al cálculo de probabilidades para poder aplicarlos posteriormente en los procesos de inferencia.En esta nueva edición se han revisado y ampliado los contenidos, incluyendo el análisis conjunto de variables cualitativas e introduciendo un nuevo capítulo dedicado al estudio de los números índices, lo que ha permitido ampliar el horizonte en el estudio descriptivo de los fenómenos aleatorios.El objetivo es facilitar al alumno la comprensión de aquellos conocimientos estadísticos a los cuales se enfrenta por primera vez en los primeros cursos de su ingeniería, licenciatura o diplomatura. Para ello, los ejercicios están resueltos de forma clara, rigurosa y completa, ofreciendo los distintos enfoques que el problema o ejercicio pueda presentar.
