Evidential Value and Interpretation

Module code: CH7203

This module builds your statistical skills for assessing the evidential value of crime scene data. The module begins with an exploration of basic statistical concepts such as data spread, confidence intervals, and hypothesis testing. It then moves into the practical application of these concepts, focusing on calculating probabilities and likelihood ratios, while also examining common fallacies in interpretation. The evidential value of DNA is investigated, with an emphasis on scenarios where DNA can be recovered and how it can contribute to a case. The module concludes by examining the impact of location and circumstances on the value of evidence.
