<P> External validity is the validity of generalized ( causal ) inferences in scientific research , usually based on experiments as experimental validity . In other words , it is the extent to which the results of a study can be generalized to other situations and to other people . Mathematical analysis of external validity concerns a determination of whether generalization across heterogeneous populations is feasible , and devising statistical and computational methods that produce valid generalizations . </P>
