Analysing data and hypothesis testing are essential skills for environmental scientists. This introductory text, based on a successful course, is written specifically to build students' confidence in applying these skills to environmental problems. The text clearly explains basic principles and provides practice in their application through worked examples and problems based on real environmental examples, while referring throughout to software programs that make calculations easy to perform.

Specialized chapters address the specific needs of environmental science students including topics such as modeling, toxicity testing, and practical advice on questionnaire design which will be especially relevant to students carrying out environmental projects. The author has also included an overview of major techniques in multivariate analysis, recognizing their importance for environmental measurements in the field where variables such as wind-speed and temperature change continuously. Analysing Environmental Data is designed for undergraduate environmental science courses on data analysis and statistics in years 1 and 2. It is intended as a primer to more advanced texts.
