This book is an exposition of statistical methodology that focuses on ideas and concepts, and makes extensive use of graphical presentation. It avoids, as much as possible, the use of mathematical symbolism. It is particularly aimed at scientists who wish to do statistical analyses on their own data, preferably with reference as necessary to professional statistical advice. It is intended to complement more mathematically oriented accounts of
statistical methodology. It may be used to give students with a more specialist statistical interest exposure to practical data analysis.
