Quizplus · Accepted Answer

The greatest threat to validity in this scenario is the interaction of selection and training. This refers to the possibility that the volunteers who participated in the study may have had different levels of experience or familiarity with software programs, which could have influenced their performance and, in turn, affected the outcome of the study. To mitigate this threat, researchers should attempt to select volunteers who are similar in relevant characteristics and provide standardized training to ensure consistency across participants.
