Employers often use standardized measures to gauge how likely it
is that a new employee with little to no experience will suceed in
thier company. One such factor is intelligence, measured using the
intelligence quotient (IQ). To show that this factor is related to
job success, an organizational pychologist measures the IQ score
and job performance (i units sold per day) in a sample of 10 new
employees
