Triangulation: the methodological approach of using multiple

Triangulation: the methodological approach of using multiple independent sources, observers, theories, or methods to validate a hypothesis or schema, where the independence of evidence sources creates meaningful convergence

Why This Is a Definition

This definition clearly identifies triangulation as a methodological framework for validation that specifically requires independence of evidence sources. It references Denzin's formalization and explicitly distinguishes it from mere replication by identifying the key requirement of independent evidence vectors that converge on the same target.

Source Lessons

L-0293

Some schemas cannot be validated directly

When direct testing is impossible look for indirect evidence and converging indicators.

L-0249

Supporting relationships build confidence

Ideas supported by multiple independent lines of evidence are more reliable.
