Essential Mathematics and Statistics for Forensic Science Summary

Essential Mathematics and Statistics for Forensic Science by Craig Adam

This text is an accessible, student-friendly introduction to thewide range of mathematical and statistical tools needed by theforensic scientist in the analysis, interpretation and presentationof experimental measurements. From a basis of high school mathematics, the book developsessential quantitative analysis techniques within the context of abroad range of forensic applications. This clearly structured textfocuses on developing core mathematical skills together with anunderstanding of the calculations associated with the analysis ofexperimental work, including an emphasis on the use of graphs andthe evaluation of uncertainties. Through a broad study ofprobability and statistics, the reader is led ultimately to the useof Bayesian approaches to the evaluation of evidence within thecourt. In every section, forensic applications such as ballisticstrajectories, post-mortem cooling, aspects of forensicpharmacokinetics, the matching of glass evidence, the formation ofbloodstains and the interpretation of DNA profiles are discussedand examples of calculations are worked through. In every chapterthere are numerous self-assessment problems to aid studentlearning. Its broad scope and forensically focused coverage make this bookan essential text for students embarking on any degree course inforensic science or forensic analysis, as well as an invaluablereference for post-graduate students and forensicprofessionals. Key features: * Offers a unique mix of mathematics and statistics topics,specifically tailored to a forensic science undergraduatedegree. * All topics illustrated with examples from the forensic sciencediscipline. * Written in an accessible, student-friendly way to engageinterest and enhance learning and confidence. * Assumes only a basic high-school level prior mathematicalknowledge.

Essential Mathematics and Statistics for Forensic Science Reviews

"The book's main selling point is its pedagogical approach to makethe contents relevant to the intended audience by usingsubject-specific examples. This is successful in the main, withexamples originating from a wide variety of areas in forensicscience, so that neither the forensic biologist nor the forensicchemist or physicist need to feel neglected. It is even morecommendable that Craig Adams manages to find a forensic context forthe development of essential skills, such as the computation ofconcentrations from spectrophotometric measurements and theplotting of standard curves for HPLC data."

About Craig Adam

Craig Adam has over twenty years experience in teaching mathematics within the context of science at degree level. Initially this was within the physics discipline, but more recently he has developed and taught courses in mathematics and statistics for students in forensic science. As head of natural sciences at Staffordshire University in 1998, he led the initial development of forensic science degrees at that institution. Once at Keele University he worked within physics before committing himself principally to forensic science from 2004. His current research interests are focused on the use of chemometrics in the interpretation and evaluation of data from the analysis of forensic materials, particularly those acquired from spectroscopy. His teaching expertise areas within forensic science, apart from mathematics and statistics, include blood dynamics and pattern analysis, enhancement of marks and impressions, all aspects of document analysis, trace evidence analysis and evidence evaluation.
