This statement is incorrect. Both internal and external validity are concerned with all types of experiments, not just laboratory or field experiments. Internal validity refers to the extent to which a study's design and methods are able to eliminate or minimize alternative explanations for the results. External validity refers to the extent to which the results of a study can be generalized to other populations or settings.
