"The First Edition of Statistical Methods for Geography provided an excellent introduction to the statistical analysis of spatial data. The second edition is even better - providing more material on probability and on descriptive statistics as well as more exercises. I would recommend this strongly as a text for introductory statistics courses in geography. It is currently the best on the market by far." Â - A. Stewart Fotheringham, National University of Ireland, MaynoothÂ The Second Edition of this bestselling text has been completely revised and updated. It provides a systematic introduction to the principal methods and techniques that students must understand to complete aÂ statistics course.Features new to this edition include: More introductory material especially in a new chapter on descriptive statistics, and much-expanded introductory chapters More exercises and illustrative examples within the chapters SPSS for Windows and EXCEL used to illustrate the applied use of the methods A companion Web site for lecturers and studentsÂ is availableÂ at www.sagepub.co.uk/rogerson . The password-protected lecturer sectionÂ contains answers to questions from the book. There are also downloadable-datasets and study skills for students.
