When the results of an experiment can be applied to real-world conditions, that experiment is said to have

Ecological validity

Step-by-step explanation:

Well, to complete the sentence, first we need to be aware of types of validity of experiments such as criterion validity, ecological validity, content validity , factorial validity, etc.
