External validity relates to the generalizability of experimental findings to the ‘real’ world. External validity refers to the relevance of the experiment, i.e. to what extent the results of the experiment apply to other environments. External validity is difficult to evaluate because of “confirmation bias” and the complexity of drawing conclusions from evidence.

modeling of experimental design is a manifestation of an ambition to avoid problem with internal validity.

The essential difference between internal and external validity is that internal validity refers to the structure of a study and its variables while external validity relates to how universal the results are.   There are further differences between the two as well.

In their 1963 book, Experimental and Quasi-Experimental Designs for Research, Donald Campbell and Julian Stanley describe two research design concepts: internal validity and external validity. Internal validity is the idea that observed differences in a dependent variable (e.g. test score) are directly related to an independent variable (e.g., participant’s true ability).

Think of this as the degree to which a result can be generalized. An empirical study is high in external validity if the way it was conducted supports generalizing the results to people and situations beyond those actually studied. It mainly focuses on naturalness. External validity is mainly concerned with the applicability of the results. Things which it measures Internal validity helps in measuring the accuracy of experiments. External validity is helpful in measuring the causal relationship between different variables of the study.
