Statistics: A First Course

The objective of Statistics is to provide a foundation in statistics. The book presents statistics at a level that is appropriate and interesting, reflected in its organization, the language used, its format and notation, and the examples used. Its high level of mathematical precision has been enhanced without complicating the presentation. Examples are found near related sections for enhanced correlation and cohesion, while review sections are designed to reinforce connections outside the context of a particular section or chapter. The book highlights important formulas, definitions, and rules in colored boxes for quick and easy reference. It also impresses upon the reader that statistical software will facilitate the techniques discussed within the book, and it is illustrated throughout with computer output. Finally, the book makes no attempt to avoid controversy, exposing readers to the weaknesses of statistical techniques along with strengths. The seventh edition of A First Course has been revised to include substantial changes in content, organization, language, notation, and format, as well as a large number of new and revised exercises. This edition also introduces the graphing calculator, which can be used to supplement or, in many cases, substitute for a computer. An important resource for every professional who responsibilities encompass statistics.
