A field experiment has the highest degree of external validity because it takes place in a real-world setting and allows for the manipulation of variables in a natural environment. This increases the likelihood that the results can be generalized to other situations and populations outside of the experiment. Laboratory experiments and concomitant experiments are typically conducted in more controlled environments and may not be as representative of real-world scenarios.
