Essential Mathematics and Statistics for Forensic Science is an accessible, student-friendly introduction to the wide range of mathematical and statistical tools needed by the forensic scientist in the analysis, interpretation and presentation of experimental measurements. From a basis of high school mathematics, it develops essential quantitative analysis techniques within the context of a broad range of forensic problems and contexts. The focus of the material is very much on the need to ensure that forensic measurements and calculations are properly and accurately carried out then communicated reliably to others. Topics such as units, understanding uncertainties, basic chemical calculations and the evaluation of formulae are clearly prominent. These are illustrated using examples from molar and dilution calculations to more specifically forensic contexts such as body cooling after death and the dependence of fly egg development on temperature. Trigonometry is especially important in forensic science through its key function in evaluating bloodstain pattern evidence as well as in ballistics.
