Reconstructing and exploring the past through archaeological evidence is not an easy or trivial task, and an absolute prerequisite for progress is the recognition of patterns in archaeological data. Rarely are these immediately apparent in the masses of material which archaeologists uncover.Quantitative methods of data analysis provide an indispensible means of detecting such patterning in a systematic and organised fashion.This book introduces archaeologists to the most important quantitative methods, from the initial description of archaeological data to techniques of multivariate analysis. These are presented in the context of familiar problems in archaeological practice, an approach designed to illustrate theirrelevance and to overcome the fear of mathematics from which archaeologists often suffer.The book arises from courses which the author has given over a number of years from first-year to Master's level. Through worked examples it will help students understand how archaeological problems can be posed in quantitative terms; how to use basic quantitative methods to analyse archaeologicaldata and how to realise when advise from experts is needed to solve specific complex problems.
