Question

Quizplus · Accepted Answer

Proper selection and assignment of subjects to groups can help control for potential confounding variables and increase the internal validity of the experimental design. While large sample size can also help with external validity, it does not necessarily address threats to internal validity. Small sample size can actually increase the risk of type II errors and limit the generalizability of the findings. While it may not be possible to completely rule out all threats to internal validity, taking steps to minimize them can improve the quality of the study.
