Quizplus · Accepted Answer

Quasi-experiments do not have the same level of control as true experiments, which can lead to potential threats to internal validity. However, an argument for the internal validity of quasi-experiments can be made by examining supplementary data and using logical analysis in addition to the results of the quasi-experiment itself. This allows for a more comprehensive evaluation of the study and helps to address potential threats to internal validity. It is not necessary to have a corresponding true experiment to make this argument.
