Measuring Behaviour is a guide to the principles and methods of quantitative studies of behaviour, with an emphasis on techniques of direct observation, recording and analysis. Numerous textbooks describe and analyse human and animal behaviour, but none provides a comprehensive review of the principles and techniques of its measurement. Those undertaking this task for the first time are often bemused by the apparent difficulty of the job facing them - how will they accurately and systematically record all that is happening? The purpose of this book is to provide this basic knowledge in a succinct and easily understood form. This concise review of methodology includes a comprehensive annotated bibliography. Written with ,brevity and clarity, Measuring Behaviour is intended, above all, as a practical guide-book.
