Estadística Descriptiva e Inferencial, es un libro que está pensado para alumnos universitarios de cualquier carrera universitaria. En él encontrarás teoría a modo de resúmenes, y problemas resueltos, de los siguientes temas: Estadística Descriptiva, Intervalos de Confianza y Contrastes de hipótesis para medias, proporciones y varianzas para una muestra, Prueba de Chi Cuadrado, Contrastes de hipótesis para medias, proporciones y varianzas para dos o más muestras, y Recta de Regresión. En la resolución de los problemas se han utilizado programas de software estadístico como SPSS, Minitab, e incluso en algunos casos se han resuelto mediante el Excel y también manualmente.
Descriptive and Inferential Statistics, is a book that is intended for university students of any college. You'll find theory as summaries, and exercises solved, on the following topics: Descriptive Statistics, Confidence Intervals and Test Hypothesis for means, proportions and variances for one sample, Chi Square Test, Test Hypothesis for means, proportions and variances, for two or more samples, and Regression line. Statistical software such as SPSS, Minitab, programs have been used in the resolution of problems and in some cases have been resolved by using the Excel and also manually.
A standard introductory textbook focusing on the scientific roots of the field while emphasizing its practical value and relevance to society. The first edition was published in 1989. Annotation copyrighted by Book News, Inc., Portland, OR
"Perspectives on Personality describes a range of viewpoints that are used by personality psychologists today, and helps students understand how these viewpoints can be applied to their own lives. Authors Charles Carver and Michael Scheier dedicate a chapter to each major perspective, presenting an overview on the perspective's orienting assumptions and core themes and concluding with a discussion of problems within that theoretical viewpoint and predictions about its future prospects. The Eighth edition incorporates several important recent developments in the field, including genetics and genomics and the biological underpinnings of impulsiveness"--Back cover
The Handbook of Research Design in Mathematics and Science Education is based on results from an NSF-supported project (REC 9450510) aimed at clarifying the nature of principles that govern the effective use of emerging new research designs in mathematics and science education. A primary goal is to describe several of the most important types of research designs that: * have been pioneered recently by mathematics and science educators; * have distinctive characteristics when they are used in projects that focus on mathematics and science education; and * have proven to be especially productive for investigating the kinds of complex, interacting, and adapting systems that underlie the development of mathematics or science students and teachers, or for the development, dissemination, and implementation of innovative programs of mathematics or science instruction. The volume emphasizes research designs that are intended to radically increase the relevance of research to practice, often by involving practitioners in the identification and formulation of the problems to be addressed or in other key roles in the research process. Examples of such research designs include teaching experiments, clinical interviews, analyses of videotapes, action research studies, ethnographic observations, software development studies (or curricula development studies, more generally), and computer modeling studies. This book's second goal is to begin discussions about the nature of appropriate and productive criteria for assessing (and increasing) the quality of research proposals, projects, or publications that are based on the preceding kind of research designs. A final objective is to describe such guidelines in forms that will be useful to graduate students and others who are novices to the fields of mathematics or science education research. The NSF-supported project from which this book developed involved a series of mini conferences in which leading researchers in mathematics and science education developed detailed specifications for the book, and planned and revised chapters to be included. Chapters were also field tested and revised during a series of doctoral research seminars that were sponsored by the University of Wisconsin's OERI-supported National Center for Improving Student Learning and Achievement in Mathematics and Science. In these seminars, computer-based videoconferencing and www-based discussion groups were used to create interactions in which authors of potential chapters served as "guest discussion leaders" responding to questions and comments from doctoral students and faculty members representing more than a dozen leading research universities throughout the USA and abroad. A Web site with additional resource materials related to this book can be found at http://www.soe.purdue.edu/smsc/lesh/ This internet site includes directions for enrolling in seminars, participating in ongoing discussion groups, and submitting or downloading resources which range from videotapes and transcripts, to assessment instruments or theory-based software, to publications or data samples related to the research designs being discussed.
In this expanded and revised edition of a fresh and original case-study textbook on environmental ethics, Christine Gudorf and James Huchingson continue to explore the line that separates the current state of the environment from what it should be in the future. Boundaries begins with a lucid overview of the field, highlighting the key developments and theories in the environmental movement. Specific cases offer a rich and diverse range of situations from around the globe, from saving the forests of Java and the use of pesticides in developing countries to restoring degraded ecosystems in Nebraska. With an emphasis on the concrete circumstances of particular localities, the studies continue to focus on the dilemmas and struggles of individuals and communities who face daunting decisions with serious consequences. This second edition features extensive updates and revisions, along with four new cases: one on water privatization, one on governmental efforts to mitigate global climate change, and two on the obstacles that teachers of environmental ethics encounter in the classroom. Boundaries also includes an appendix for teachers that describes how to use the cases in the classroom.
No one disputes how important it is, in today's world, to prepare students to un derstand mathematics as well as to use and communicate mathematics in their future lives. That task is very difficult, however. Refocusing curricula on funda mental concepts, producing new teaching materials, and designing teaching units based on 'mathematicians' common sense' (or on logic) have not resulted in a better understanding of mathematics by more students. The failure of such efforts has raised questions suggesting that what was missing at the outset of these proposals, designs, and productions was a more profound knowledge of the phenomena of learning and teaching mathematics in socially established and culturally, politically, and economically justified institutions - namely, schools. Such knowledge cannot be built by mere juxtaposition of theories in disci plines such as psychology, sociology, and mathematics. Psychological theories focus on the individual learner. Theories of sociology of education look at the general laws of curriculum development, the specifics of pedagogic discourse as opposed to scientific discourse in general, the different possible pedagogic rela tions between the teacher and the taught, and other general problems in the inter face between education and society. Mathematics, aside from its theoretical contents, can be looked at from historical and epistemological points of view, clarifying the genetic development of its concepts, methods, and theories. This view can shed some light on the meaning of mathematical concepts and on the difficulties students have in teaching approaches that disregard the genetic development of these concepts.
This volume contains 34 articles on the economics of altruism published after 1975. The articles are grouped under 6 headings: the emergence of altruistic behaviour, varieties of altruism, the relevance of altruism and selfishness, altruism and allocation of resources, evolutionary dynamics of altruism, extended rationality and altruistic behaviour. It should be welcomed by all those with an interest in economics, philosophy, psychology and sociology.
