The Daubert Standard is a set of criteria used by US federal courts to assess the admissibility of scientific expert testimony.
Step 1: Recall the core factors of the Daubert Standard. The key criteria are:
- Testability: Can the scientific theory or technique be empirically tested? (Matches option 1)
- Peer Review and Publication: Has the methodology been subjected to peer review and published in scientific literature? (Matches option 3)
- Error Rate: What is the known or potential error rate of the method? (Matches option 4)
- General Acceptance: Is the technique generally accepted in the relevant scientific community? (This was the older Frye standard, but it is still considered a factor under Daubert).
Step 2: Evaluate the given options. Options (1), (3), and (4) are all explicit factors of the Daubert Standard. Option (2), concerning international certification of the expert, is not a specific criterion. While an expert's qualifications are assessed, the Daubert standard focuses on the {methodology}, not the expert's personal certifications.
