Key aspects:
🔍 Relevance: The extent to which the evidence pertains to the matter under investigation.

⚖️ Reliability: Whether the evidence is trustworthy, authentic, and obtained through valid means.

📚 Weight: How persuasive or impactful the evidence is in supporting a conclusion or argument.

In context:
In law, a witness statement may have high evidentiary value if it's consistent, corroborated, and directly related to the case.

In science, a randomized controlled trial has higher evidentiary value than a case report due to its methodological rigor.
