The fourth edition of this widely-used text has been fully updated to include the latest official statistics and a new chapter on simulation. Presented in a larger format, with 2-colour text, the book maintains the successful formula of previous editions and continues to cater mainly for students taking the first year examinations of major professional bodies. It provides them with a comprehensive introduction to statistics in business and relates the illustrations and examples to the student's own experience. Before any concept is introduced, the need for it is fully discussed and great emphasis is laid on its interpretation.  In addition to numerous fully-worked examples the text contains more than 350 exercises from appropriate examinations boards and is accompanied by a students' workbook, software disk and Instructor's Manual.  The software disk is available free to lecturers adopting the title and includes the new versions of Lotus 1-2-3 and Aseasyas.
