About this mock
This test probes advanced statistical reasoning as applied to the evaluation of forensic evidence. Questions address the hierarchy of propositions (source, activity, and offence levels), the correct formulation and interpretation of likelihood ratios for complex evidence including mixed DNA profiles, the island and database problems, and the transposed conditional fallacy. Topics also include the calibration of verbal scales for communicating strength of evidence, receiver-operating-characteristic analysis and error-rate interpretation, and modern guidance from bodies such as the European Network of Forensic Science Institutes and the Forensic Science International journal series. Candidates are expected to apply these principles analytically to fact patterns, distinguish between closely related but logically distinct concepts, and identify reasoning errors that arise in casework and court settings. A firm grasp of probabilistic logic, Bayesian inference, and contemporary evaluative practice is required to perform well.
