Statistical techniques for the presentation and analysis of biological data are indispensable tools for the biologist. The purpose of this book is to develop students' appreciation and understanding of statistical usage with the Biosciences and to equip them with the ability to apply statistical methods and the reasoning as an integral aspect of analysis and interpretation of experimental data. Emphasis is placed on where these techniques fit into the overall interpretational objectives of data analysis. Rather than concentrating on the mathematical aspects of the techniques described, this book provides the reader with practical illustrations of data handling.
