External Validity identifies the correctness of the research findings, by examining its applicability from one setting to another. Threats to external validity take place when the specific set of research conditions does not practically consider the interactions of other variables of the real world. External validity External validity refers to the extent to which the results of a study can be generalized beyond the sample. Which is to say that you can apply your findings to other people and settings.
