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.
Internal Validity. Internal validity is a measure which ensures that a researcher's experiment design closely follows the principle of cause and effect. Test Validity. Test validity is an indicator of how much meaning can be placed upon a set of test results.
