Understanding internal and external validity”.
External validity: an extent to which research results can be generalised beyond the specific situation studied.
The concepts of internal and external validity were first introduced by Campbell(1957).
The first objective stresses on internal validity, whereas the second focuses on external validity.
Finally, external validity centers around whether the results of this experiment would generalize to other situations.
For most well-designed and well-run experiments, concerns about external validity are the hardest to address.

The size of the large sample(about 400,000 children aged 6- 8)helped to establish external validity of the results.
Finally, external validity centers around whether the results of this experiment can be generalized to other situations.
For most well-designed and well-run experiments, concerns about external validity are the hardest to address.
Another aspect of external validity is whether alternative operationalizations of the same intervention will have similar effects.
Fortunately, the digital age enables researchers to movebeyond these data-free speculations and assess external validity empirically.
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.
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. .
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.

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.
This wide review carefully evaluated the studies conducted, both in terms of quality of design and execution(called"internal validity") and how appropriate each was for theway that homeopathy is commonly practiced(called"external validity").
First, researchers willbe 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.

The subject of external validity is of special importance because some scientists and physicians conduct research on homeopathy with little or no understanding of this type of medicine(some studies tested a homeopathic medicine that is rarely used for the condition tested, while others utilized medicines not commonly indicated for specific patients).
The four types of validity- statistical conclusion validity, internal validity, construct validity, external validity- provide a mental checklist to help researchers assess whether the results from a particular experiment support a more general conclusion.

The idea of mediators is captured 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).
