Question

Quizplus · Accepted Answer

Including data for close calls can improve the validity of incident measures of training effectiveness because it provides insight into the effectiveness of the training in preventing potential accidents or incidents. Close calls are also important as they can alert organizations to potential areas of weakness within their training programs. Excluding data for close calls would result in an incomplete picture of the effectiveness of the training. Segregation of data by type of worker and job may be useful for other types of analysis, but does not necessarily improve the validity of incident measures of training effectiveness.
