Available in PDF, EPUB and Kindle. Book excerpt: La estadística es una rama de las matemáticas que se encarga de recolectar, analizar, describir e interpretar datos. Sus aplicaciones se han convertido en el centro del desarrollo de la ciencia y la tecnología en el siglo XX y el siglo XXI. La irrupción de la era digital ha permitido un avance en ciertos campos de estudio relacionados con la estadística aplicada, como lo son: la ciencia de datos, Machine Learning, Big Data, actuaría, entre otras. Por ende, se ha generado un gran interés en estudiar y profundizar los modelos estadísticos detrás de estas áreas.La estadística es una herramienta poderosa para desarrollar el conocimiento científico, generar predicciones y desvelar resultados concluyentes sobre un conjunto de datos determinado. Sin embargo, es importante para cualquier individuo tener un conocimiento de estadística. La necesidad de lo anterior surge pues el desconocimiento de estas herramientas puede llevar a engaños y manipulación. Esto se puede resumir en una frase célebre del autor Estadounidense Mark Twain: "Hay tres clases de mentiras, mentiras, malditas mentiras y las estadísticas".En el capítulo 1 se motiva el estudio de la estadística, además de introducirse conceptos preliminares como proporción, porcentaje o tasa que serán necesarios para capítulos posteriores. En el capítulo 2 se introduce uno de los conceptos más importantes de la estadística: la variable. Se muestran además las diferentes formas de clasificar variables y algunos ejemplos. En el capítulo 3 se comienza el estudio descriptivo de variables cuantitativas mediante algunas métricas como medidas de tendencia central y dispersión.En el capítulo 4 se expanden los análisis del capítulo 3 y se explica la elaboración de resúmenes gráficos de variables cuantitativas. En el capítulo 5 se realiza un resumen gráfico para variables cualitativas mostrando las construcciones visuales más utilizadas. Finalmente, en el capítulo 6 se presentan algunos ejercicios propuestos para evaluar el manejo de los conceptos del texto. Por otro lado, el texto cuenta con dos apéndices. En el apéndice A se estudia la metodología de la investigación en estadística, mostrando los pasos y motivación además de algunos ejemplos. En el apéndice B se definen algunos términos en la estructura de la teoría matemática que pueden ser útiles para comprender algunos términos del presente texto.Con este texto se espera que se de una introducción a la estadística descriptiva y resulta útil como el primer encuentro con estadística para personas de distintas disciplinas así como para personas con buen manejo de la rigurosidad matemática.

Download or read book The History of Water Management in the Iberian Peninsula written by Ana Duarte Rodrigues and published by Springer Nature. This book was released on 2020-03-18 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume approaches the history of water in the Iberian Peninsula in a novel way, by linking it to the ongoing international debate on water crisis and solutions to overcome the lack of water in the Mediterranean. What water devices were found? What were the models for these devices? How were they distributed in the villas and monastic enclosures? What impact did hydraulic theoretical knowledge have on these water systems, and how could these systems impact on hydraulic technology? Guided by these questions, this book covers the history of water in the most significant cities, the role of water in landscape transformation, the irrigation systems and water devices in gardens and villas, and, lastly, the theoretical and educational background on water management and hydraulics in the Iberian Peninsula between the sixteenth and the nineteenth centuries. Historiography on water management in the territory that is today Spain has highlighted the region’s role as a mediator between the Islamic masters of water and the Christian world. The history of water in Portugal is less known, and it has been taken for granted that is similar to its neighbour. This book compares two countries that have the same historical roots and, therefore, many similar stories, but at the same time, offers insights into particular aspects of each country. It is recommended for scholars and researchers interested in any field of history of the early modern period and of the nineteenth century, as well as general readers interested in studies on the Iberian Peninsula, since it was the role model for many settlements in South America, Asia and Africa.

Download or read book My Word written by Susan D. Blum and published by Cornell University Press. This book was released on 2011-06-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Classroom Cheats Turn to Computers." "Student Essays on Internet Offer Challenge to Teachers." "Faking the Grade." Headlines such as these have been blaring the alarming news of an epidemic of plagiarism and cheating in American colleges: more than 75 percent of students admit to having cheated; 68 percent admit to cutting and pasting material from the Internet without citation. Professors are reminded almost daily that many of today's college students operate under an entirely new set of assumptions about originality and ethics. Practices that even a decade ago would have been regarded almost universally as academically dishonest are now commonplace. Is this development an indication of dramatic shifts in education and the larger culture? In a book that dismisses hand-wringing in favor of a rich account of how students actually think and act, Susan D. Blum discovers two cultures that exist, often uneasily, side by side in the classroom. Relying extensively on interviews conducted by students with students, My Word! presents the voices of today's young adults as they muse about their daily activities, their challenges, and the meanings of their college lives. Outcomes-based secondary education, the steeply rising cost of college tuition, and an economic climate in which higher education is valued for its effect on future earnings above all else: These factors each have a role to play in explaining why students might pursue good grades by any means necessary. These incentives have arisen in the same era as easily accessible ways to cheat electronically and with almost intolerable pressures that result in many students being diagnosed as clinically depressed during their transition from childhood to adulthood. However, Blum suggests, the real problem of academic dishonesty arises primarily from a lack of communication between two distinct cultures within the university setting. On one hand, professors and administrators regard plagiarism as a serious academic crime, an ethical transgression, even a sin against an ethos of individualism and originality. Students, on the other hand, revel in sharing, in multiplicity, in accomplishment at any cost. Although this book is unlikely to reassure readers who hope that increasing rates of plagiarism can be reversed with strongly worded warnings on the first day of class, My Word! opens a dialogue between professors and their students that may lead to true mutual comprehension and serve as the basis for an alignment between student practices and their professors' expectations.

Download or read book The Indigenous Languages of South America written by Lyle Campbell and published by Walter de Gruyter. This book was released on 2012-01-27 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Indigenous Languages of South America: A Comprehensive Guide is a thorough guide to the indigenous languages of this part of the world. With more than a third of the linguistic diversity of the world (in terms of language families and isolates), South American languages contribute new findings in most areas of linguistics. Though formerly one of the linguistically least known areas of the world, extensive descriptive and historical linguistic research in recent years has expanded knowledge greatly. These advances are represented in this volume in indepth treatments by the foremost scholars in the field, with chapters on the history of investigation, language classification, language endangerment, language contact, typology, phonology and phonetics, and on major language families and regions of South America.
