Random assignment enhances the generalizability of a study.

Question

Quizplus · Accepted Answer

Random assignment enhances the internal validity of a study by ensuring that each participant has an equal chance of being assigned to any group, thus controlling for confounding variables. Generalizability, or external validity, is more related to how well the results can be applied to contexts outside of the study, which is influenced by factors like sample diversity and setting, rather than random assignment.
