In fact, your sample size should be based on calculating power considerations (e.g., simulation), not "balancing" internal and external validity. Internal validity centers on whether there is a causal relationship between the When conducting research, why is there often a trade-off between internal and external validity? Is there a benefit in achieving a high level of one type of validity (internal versus external) over the other? Is there a way to design a study or series of studies to have high internal as well as high external validity? What would be the benefit What that means is one of the big strengths of human studies is high external validity. Now, weaknesses for human studies, we have less control, less experimental control over alternative explanations. And typically lower internal validity.

1. What is the tradeoff between internal and external validity? In management research to which do you preponderate in general?

To increase internal validity, we tend to use random assignment to treatment and control groups (discussed in Campbell's paper). The idea is that random assignment randomly distributes all sorts of confounding variables that you haven't accounted for among both groups, so they should be equally balanced (or, if they're not, it was by random chance). To increase external validity, we tend to use random sampling to collect our participants. The idea is that random sampling grabs a 1.

So far, we have outlined the importance that is accorded to the validity of data and pointed to the inherent trade-off between internal and external validity. What that means is one of the big strengths of human studies is high external validity. Now, weaknesses for human studies, we have less control, less experimental control over alternative explanations. And typically lower internal validity. So that's the trade-off between external and internal validity. 1.
