Evidence

Evidence consists of facts, data, examples, and expert opinions that support your claims. Without strong evidence, arguments become mere opinions.

Types of Evidence

  • Statistical — numerical data and research findings
  • Expert testimony — opinions from recognized authorities
  • Anecdotal — personal stories and specific examples
  • Historical — past events and established patterns
  • Case studies — detailed analysis of specific examples
