In research, the ecological validity of a study means that the methods, materials and setting of the study must approximate the real-world that is being examined. Unlike internal and external validity, ecological validity is not necessary to the overall validity of a study.
Validity is the extent to which a concept, conclusion or measurement is well-founded and corresponds accurately to the real world. The word valid is derived from the Latin validus, meaning strong. The validity of a measurement tool (for example, a test in education) is considered to be the degree to which the tool measures what it claims to measure; in this case, the validity is an equivalent to accuracy.
