Descriptive Statistics 
Descriptive Statistics is available as a paperback book at £8.50 and also as an integrated multimedia teaching program and ebook that can be downloaded and installed for only£6. The book has the same lighthearted style as the program, enlivened by many cartoons. It explains the principles and the methods for summarizing and describing data in numbers and in graphs. The computer program covers the same material in a different way. It contains Sections 2, 3, 4 and 8 of Introduction to Statistics along with its Demo and Glossary. Within the program, a Read Book button opens the electronic book at a page relevant to the current topic. You can then browse the book or return to the program at the point where you left it.
