Designed for anyone who needs a comprehensive introduction to the principles of statistical methods and their applications, this text is written in a practical, non-threatening style. Step-by-step worked examples are used to illustrate the use of statistical techniques in solving practical problems while self-study exercises test students' knowledge. The use of Excel and MINITAB is fully integrated throughout the book to demonstrate the application of computer packages to solve a wide range of statistical problems. Presented alongside manual methods, these computer solutions include detailed instructions and annotated print outs where appropriate. The second edition retains the straightforward writing style and practical illustration of manual and computer methods which made the previous book successful for a wide range of courses.
