"This book present graphical methods for analysing data. Some methods are new and some are old, some require a computer and others only paper and pencil; but they are all powerful data analysis tools. In many situations, a set of data? even a large set- can be adequately analyses through graphical methods alone. In most other situations, a few well-chosen graphical displays can significantly enhance numerical statistical analyses."--Provided by publish
