Ecological validity is a form of validity in a research study. For a research study to have ecological validity, 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.

Famous quotes containing the words ecological and/or validity:
“The hatred of the youth culture for adult society is not a disinterested judgment but a terror-ridden refusal to be hooked into the, if you will, ecological chain of breathing, growing, and dying. It is the demand, in other words, to remain children.”
—Midge Decter (b. 1927)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
