This hampers the external validity to the general population.
For most well-designed andwell-run experiments, concerns about external validity are the hardest to address.
One aspect of external validity is the setting where an intervention is tested.
Fortunately, the digital age enables researchers to move beyond these data-free speculations and assess external validity empirically.
There are questions about the external validity of the AS diagnosis.
Finally, external validity centers around whether the results of this experiment would generalize to other situations.
In this way, it provides the entrepreneur and the investor with the assessment of the external validity and consistency of the business idea see Figure 1.
Finally, external validity centers around whether the results of this experiment can be generalized 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.
The concepts of internal and external validity were first introduced in Campbell 1957.
After the assessment of the external validity and consistency of the opportunity, attention should turn to a description of the resources the entrepreneur needs to bring his business idea into reality see Part 3 on Figure 1.
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.
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, 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 is captured by what I call mechanisms, andthe 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.
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.
