Internal Validity¶. As described above, internal validity is about whether we think a study has accurately interpreted the case it is studying. In the context of causal inference, this amounts to asking whether the study properly estimated the causal effect studied for the set of entities it was focused on.

Internal validity refers to the degree of confidence that the causal relationship being tested is trustworthy and not influenced by other factors or variables. External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. The language of internal and external validity is not used by everyone, but many of us would agree that intuitively the distinction makes a lot of sense.

In other words, internal validity focuses on threats or rival explanations that influence the outcomes of an experimental study but are not part of the independent variable. Table 13.1 Threats to Internal Validity Internal validity is the most important requirement, which must be present in an experiment, External Validity Applicability of evaluation results to other populations, setting and time periods is often a question to be answered once internal validity threats have been eliminated or minimized. Below is a selection of external threats that can help guide your conclusions on the generalizability of your research results: 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.
