Improving Experimental Design: Ethical Implications and How the Experimental Design Assistant (EDA) Can Help

Audience: This program is tailored to IACUC staff, IACUC members, IOs, veterinarians, investigators, compliance personnel, animal care staff, and others involved in animal programs.

Speaker: Esther Pearl, PhD, Programme Manager for Experimental Design, National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs)


Join us as we explore the NC3Rs Experimental Design Assistant (EDA)! The EDA helps users build a diagram representing an experimental plan, provides customized feedback, and can make suggestions on statistical methods, randomization, blinding, sample sizes, and other critical design aspects. Dr. Esther Pearl, NC3Rs Programme Manager for Experimental Design, discusses how the EDA can assist research staff, how it can simplify protocol review for IACUCs, and demonstrates features of this free resource. 

Learning Objectives Include:

  • Understand why we need to improve experimental design
  • Identify key ways to improve biomedical research
  • Know what the Experimental Design Assistant (EDA) is and its benefits to researchers
  • Understand how the EDA can be used as part of the ethical review process
