About this mock
This test covers the foundational statistical concepts that underpin forensic evidence evaluation worldwide. Topics include basic probability rules, the distinction between independent and conditional probability, descriptive statistics (mean, median, mode, variance, standard deviation), common probability distributions, and the difference between populations and samples. An understanding of these principles is essential for interpreting DNA match statistics, toolmark frequency data, fiber transfer probabilities, and trace-evidence significance in casework. Questions draw on internationally recognised statistical frameworks used by forensic laboratories in the United States, United Kingdom, Europe, and beyond. No advanced mathematics is required: the focus is on conceptual recognition, correct terminology, and the practical role statistics plays in communicating certainty and uncertainty to courts and investigators. Suitable for students and practitioners beginning their study of quantitative reasoning in forensic science.
