Textbook in PDF format

This textbook and the accompanying software are written from different perspectives and with different users in mind. We believe that the main users of the book and software will be business and social science students taking an introductory course in statistics at undergraduate level. It may also be relevant for postgraduate MBA students.
One of the main difficulties in teaching statistics at these levels is coping with the motivation and mathematical ability of the students. We have tried to address the problem of motivation by using a large number of articles and graphs from newspapers and websites within the areas of business, economics, social science and everyday life. Generally each chapter of the book and each software module is application-motivated rather than just having an example to illustrate the technique.
As a minimum we expect that the vast majority of students will have a mathematical qualification from school at the Standard grade, in Scotland, or GCSE grade in England, Wales and Northern Ireland. For some of the chapters this level of mathematical ability is not necessary, but other chapters have more advance mathematics. A large number of students will have an A level, AS level or Scottish Higher qualification in mathematics, and we hope that the book has sufficient mathematical detail for such students.
