While there are inherent threats to internal validity in quasi-experiments, it is possible to make an argument for their internal validity by using supplemental data and logical analysis in addition to the results of the quasi-experiment itself. This can help address some of the limitations and potential confounding variables that exist in quasi-experimental designs. However, it is important to note that a corresponding true experiment can provide stronger evidence for internal validity.
