Abstract

The work, now in its second edition published in 2025, presents itself as a novel and indispensable contribution to the national technical-scientific literature focused on the analysis of uncertainties in the variables used in traffic accident reconstruction. Written by the experts Dr. Wilson Toresan Jr. and Nortthon Didyk / ACTAR, the book fills a historical gap by addressing, in a didactic and technically precise manner, the use of statistics in the quantification of uncertainties, data modeling, and interpretation of forensic variables.

The content, aimed at criminal and private experts, is organized into ten chapters, structured in two complementary parts. The first part covers the fundamentals of statistics; the second addresses its practical applications in the context of traffic expert examinations:

1. Basic Concepts of Statistics;
2. Descriptive Statistics;
3. Inferential Statistics;
4. Probability Distributions;
5. Hypothesis Testing;
6. Linear Regression;
7. Analysis of Variable Uncertainties;
8. Sensitivity of Calculation Results;
9. Additional Applications of Concepts;
10. Presentation of Results in the Expert Report.

The main virtue of the work lies in the integration between statistical theory and the real challenges faced by experts in practice. The reader is guided to understand how statistical concepts — often considered abstract — are essential in the analysis of uncertainties, interpretation of experimental data, and technical communication in forensic reports.

The book also covers applied computational aspects, with clear guidance on the use of electronic spreadsheets, specifically Microsoft Excel 365®, providing accessible and practical tools for daily expert work.

It is essential reading for criminalistics professionals, researchers, engineers, and students in the field, establishing itself as a national reference in the teaching and application of forensic statistics in the context of traffic accident reconstruction.
