- The validity of applying the conclusions of a scientific investigation outside the framework of that study is known as external validity.
- In other words, it is the degree to which a study's findings can be generalized to and across other settings, persons, stimuli, and times.
- Internal validity, on the other hand, is the validity of results drawn within the framework of a certain study.
- External validity is an important quality of any study because general conclusions are virtually always a goal in research.
