Forensic Statistics
Learning Opportunities

Our learning opportunities help amplify existing knowledge and build new competencies

  • Learn statistical concepts as they apply to the evaluation of pattern and digital evidence 
  • Discuss challenges and how to overcome them in your daily work

Sampling for Forensic Practitioners

Three-part course covering populations, sampling frames, sampling methods and geometric sampling. The emphasis will be on understanding how these methods are used to aid and enhance current forensic science practices.


  • Friday, March 25, Noon – 2 p.m. CT
  • Friday, April 1, Noon – 2 p.m. CT
  • Friday, April 8, Noon – 2 p.m. CT

Led by Alicia Carriquiry
Iowa State University

Participants who complete a full course receive a Certificate of Completion through the Center for Statistics and Applications in Forensic Evidence
