1. Avondale Industries' training and development office was trying to assess whether their training for new sales personnel for the avionics division was effective. The office set up training for three of the sites, two in the US and one abroad and did not provide training for the remaining three sites, also two in the US and one abroad. A pretest was given to all new sales personnel in the training as well as to those who were not trained. All other job tasks remained the same, and supervisors were instructed to proceed as normal with onboarding their employees. After a month of training, the performance of the new sales personnel in the two groups were compared. Results showed that the sales personnel that were trained outperformed those not trained by 29 percent. Which statement best explains why this experiment was helpful for the training and development office?

• It helped the training and development office by establishing a testable hypothesis about whether the training would be effective, which it was.
• The experiment helped the training and development office by giving them the ability to compare alternatives.
• The experiment allowed the training and development office to determine if the training was effective by mostly ruling out alternative reasons for job improvement.
• It was helpful for the training and development office to see that the results were positive for those who received the training versus those who did not.
