Aim:
After completing the course students should be able to understand and use statistical models to assess the value of evidence in results from different types of forensic analysis. This means that students will be expected to be be able to do the following upon completion of this course:
  • Formulation of prosecutor's and defender's hypotheses at source level and activity level. >/li>
  • Application of the likelihood ratio to particular cases where observed relative frequencies are given.
  • Determination of sample sizes when sampling from a seizure of discrete units.
  • Identification of common fallacies in the process of evidence evaluation.
  • Calculation of DNA profile frequencies given allelic or genotype frequencies.
  • Calculation of paternity indices given allelic or genotype frequencies.
