Calculating Basic Statistical Procedures in SPSS - 2011-04-03

Calculating Basic Statistical Procedures in SPSS: A Self-Help and Practical Guide to Preparing Theses, Dissertations, and Manuscripts, is authored by John R. Slate and Ana Rojas-LeBouef from Sam Houston State University and endorsed by the NCPEA. The textbook was written to make statistical analysis less threatening and less anxiety-producing than many persons find it to be. The authors have written this textbook in hopes of facilitating individuals’ success in using SPSS for their statistical analyses; in interpreting the SPSS output properly; and in writing statistical results correctly.

This book will assists graduate students and faculty members, as well as undergraduate students, in their use of the Statistical Package of the Social Sciences-PC (SPSS-PC) versions 15-19. Specifically, we have generated a set of point-and-click steps and screenshots to depict each important step in conducting basic statistical analyses. Additionally, model writeups of statistical results were developed because many students have extensive difficulties in describing statistical results in a meaningful manner. By following the step-by-step nature of each model writeup, readers will be able to write their own results section in a manner compliant with APA 6th edition.

Business Fundamentals - 2010-11-03

The Business Fundamentals is designed to introduce students, particularly those in developing economies, to the essential concepts of business and other organizations. It focuses on small, entrepreneurial start-ups, and expands the discussion in each chapter to include issues that are faced in larger organizations. Traditional business models are discussed as well as eBusiness models. All major functional areas of modern organizations are covered.

The Global Text Project developed business fundamentals as a proof of concept text, based on the realization that it is a mistake to teach information systems in a vacuum, without giving students an appreciation of the organizational settings in which they operate. Accordingly, a table of contents was prepared and volunteers were recruited to serve as chapter editors and reviewers for a book on business fundamentals. Most chapter editors are academics who wrote their own chapters while, in other cases, teams of graduate students wrote segments of a chapter as a part of a course assignment. All contributions are gratefully acknowledged and the contributors' names are noted at the beginning of each chapter.

Sound Reasoning - 2010-08-23

Long time music author Anthony Brandt adds a new section to his collection, "Sound Reasoning". "Hearing Harmony" is an introductory course on harmony in Western classical music. It is entirely listening based; no ability to read music is required. Aural examples are interpolated directly into the text. "Listening Galleries" provide exercises to strengthen users' confidence. "Hearing Harmony" takes a non-traditional approach: Instead of focusing on chord identification, it puts a priority on harmonic structure. The goal is to provide an accessible and rewarding resource that uses a minimum of technical language and deepens one's appreciation of classical music. "Hearing Harmony" can be used as a stand-alone course; it is also compatible with standard music appreciation and harmony courses, either as preparation or a companion text.

High Performance Computing - 2009-11-16

The purpose of Chuck Severence's book, High Performance Computing has always been to teach new programmers and scientists about the basics of High Performance Computing. This book is for learners with a basic understanding of modern computer architecture, not advanced degrees in computer engineering, as it is an easily understood introduction and overview of the topic.

Originally published by O'Reilly Media in 1998, the book has since gone out of print and has now been released under the Creative Commons Attribution License on Connexions.

"The Mars Global Surveyor orbits our nearest planetary neighbor on a mission to map the surface of Mars and catalogue scientific data. The motion of this spacecraft is managed by a propulsion system that consists of a main engine and 8 "attitude-control" thrusters. How do these propulsion devices work together to safely control the movement of the Surveyor spacecraft?"
