This is what is called external validity.
One aspect of external validity is the setting in which an intervention is tested.
This is necessary for both internal and external validity of the study.
One aspect of external validity is the setting in which an intervention is tested.
For most well-designed and well-run experiments,concerns about external validity are the hardest to address.
External validity: The study would deliver the same results even when applied to a different population.
The concepts of internal and external validity were first introduced in Campbell(1957).
External validity examines whether the study findings can be generalized to other contexts.
Fortunately, the digital age enables researchers to move beyond these data-free speculations and assess external validity empirically.
Finally, external validity centers around whether the results of this experiment would generalize to other situations.
Compared to analog age experiments,in digital age experiments it should be easier to address external validity empirically and it should be easier to ensure internal validity. .

Another aspect of external validity is whether alternative operationalizations of the same intervention will have similar effects.
See Shadish, Cook, and Campbell(2001) for a more detailed history and a careful elaboration of statistical conclusion validity, internal validity, construct validity, and external validity.
External validity refers to the extent to which the results of a study can be generalized to other situations and to other people.
The fact that the same pattern appeared in many systems increases the external validity of these results because it reduces the chance that this pattern is an artifact of any particular system.
External validity refers to the extent to which a study's conclusions can be confidently generalised to other situations and people.
The fact that the same pattern appeared in many systems increases the external validity of these results because it reduces the chance that this pattern is an artifact of any particular system.
See Shadish, Cook, and Campbell(2001) for a more detailed history and a careful elaboration of statistical conclusion validity, internal validity, construct validity, and external validity.
Further, it is important to consider methodological limitations,such as a lack of external validity of analytical and experimental research, and survey results can be biased by personal motives and experiences.
In the past, these debates about external validity were frequently just a bunch of people sitting in a room trying to imagine what would have happened if the procedures were done in a different way, or in a different place, or with different people.
The four types of validity- statistical conclusion validity, internal validity, construct validity, and external validity- provide a mental checklist to help researchers assess whether the results from a particular experiment support a more general conclusion.
In the past, these debates about external validity frequently involved nothing more than a group of people sitting in a room trying to imagine what would have happened if the procedures had been done in a different way, or in a different place, or with different participants.
The idea of mediators iscaptured by what I call mechanisms, and the idea of moderators is captured by what I call external validity(e.g., would the results of the experiment be different if it were run in different situations) and heterogeneity of treatment effects(e.g., are the effects larger for some people than for others).
The same threats to internal and external validity that beset clinical research are found in abundance in animal studies: lack of randomisation, blinding, and allocation concealment; selective analysis; and reporting and publication bias.

Epidemiological studies generally have high levels of external validity, insofar as they accurately describe events as they occur outside of a laboratory setting, but low levels of internal validity, since they do not strongly establish cause-and-effect relationships between the behaviors or conditions under study, and the health consequences observed.
First, researchers will be able to empirically address concerns about external validity when the cost of running experiments is low, and this can occur if the outcome is already being measured by an always-on data system.
