Definition

Based on observation or experience rather than theory.

Empirical describes knowledge or results that come from observing, measuring, or experimenting. It contrasts with ideas based only on logic, tradition, or speculation. In science and research, empirical evidence is collected through real-world data and careful testing.

Examples

  • The policy was changed after empirical evidence showed it was not working.
  • Her conclusion is based on empirical data from three experiments.
  • We need empirical results, not just opinions.
  • The study provides empirical support for the new method.

Common mistake

Learners often use empirical to mean "emotional" or "personal," but it means based on observation and measurable evidence.
