Question

Quizplus · Accepted Answer

Informally interviewing subjects at the end of an experiment can provide insight into whether they understood and followed experimental instructions. This can help researchers evaluate the internal validity of their experiment by identifying any potential sources of confusion or error. A panel of judges rating instructions on clarity or statistically analyzing discarded data may also be helpful, but they do not directly address whether subjects followed instructions during the actual experiment. Performing a replication study can help establish external validity but does not address internal validity.
