In a discussion of the education level of the American workforce, a researcher says, "The average young person can't even balance a checkbook." The National Assessment of Educational Progress says that a score of 275 or higher on its quantitative test reflects the skill needed to balance a checkbook. The NAEP random sample of 840 young men had a mean score of 272.
