Problem solving

Problem Solving sets out to clarify the general principles involved in tackling real-life statistical problems in an approachable and practical way. The book is written for the student or practitioner who has studied a range of basic statistical techniques but feels unsure about how to tackle a real problem, particularly when data are 'messy' or the objectives are unclear. This book is in two Parts. The first Part illuminates the complex process of problem solving, including formulating the problem, collecting and analysing the data and finally presenting the conclusions. Report-writing, consulting and using the computer are among the topics covered and the exciting potential for using relatively simple techniques is particularly emphasized. The second Part consists of a large number of exercises and case studies which are problem-based, rather than focused on specific techniques, as in most other textbooks. Working through the exercises, with the aid of helpful solutions, the reader should develop an understanding of data and a range of skills including the ability to communicate. The book concludes with extended appendices giving a valuable reference summary of required statistical topics and some notes on the MINITAB and GLIM computer packages. This new edition includes new material on Avoiding statistical pitfalls, based on a discussion paper in Statistical Science and Part One has been thoroughly revised and extended. New examples and exercises have been added and the references have been updated throughout.
