The book will cover a number of legal cases where statistical evidence helped to clarify the issues, determine the relevance and value of evidence, and understand the application of the relevant law to particular situations. It will explain the role of data and the analysis of data in public policy formulation and application in such fields as employment, education, health, the environment, finance, and criminal justice. The book will be organized in chapters that can stand alone but as a whole also will demonstrate the need for statistical thinking and practice to play a central role in enhancing public understanding of strategic planning and implementation of the legal system.
