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.
Please note that validity discussed here is in the context of experimental design, not in the context of measurement. 1  Internal validity refers specifically to whether an experimental treatment/condition makes a difference or not, and whether there is sufficient evidence to support the claim. External validity refers to the generalizibility of the treatment/condition outcomes.
