External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. The key difference between internal and external validity is that internal validity is the extent to which the researcher is able to make the claim that no other variables except the one he is studying caused the result whereas external validity is the extent to which results of a study can be generalized to the world at large. Internal validity is concerned with control of extraneous variable, whereas external validity stresses on the applicability of the outcome to the practical situations. Internal validity ascertains the strength of the research methods and design. Conversely, external validity examines the generality of the research outcomes to the real world.

The key difference between internal and external validity is that internal validity is the extent to which a researcher will be able to make the claim that no other variables, except the one he’s studying, caused the result; whereas external validity is the extent to which results of the research can be generalized because of involvement of more than one variables. internal validity) we are making the experiment more and more artificial and thereby it’s generalizability (external validity) suffers. An exception would be in reference to specific control techniques e.g. the balance technique would allow for more generalizability than would the eliminate or hold constant techniques The information needed to determine the internal and external validity of an experimental study is discussed. Internal validity is the degree to which a study establishes the cause-and-effect relationship between the treatment and the observed outcome. Establishing the internal validity of a study is based on a logical process. External and Internal Validity !
