A significant problem within the legal profession is that many of the lawyers litigating cases and the judges deciding them have only a limited understanding of how to properly interpret empirical evidence.

Trial by Numbers provides an easy way for members of the legal profession to acquire a basic understanding of the most common methods that serve as the building blocks for empirical evidence in academic articles, policy briefs, and expert witness reports. Adam Chilton and Kyle Rozema take a different approach to other introductory books on empirical methods, omitting the formulas and equations found in other books, and instead focusing on explaining the intuition and logic of common empirical methods. The work also exclusively use examples that are relevant to law school and legal practice.
