Sales manager Jake did not attend a training session before using a new selection instrument. Thus when scoring job-related skills for job candidates, he completed the evaluation forms based on his intuitive judgement rather than objectively evaluating each candidates level of skills. This is an example of measurement errors caused by :

the job candidate who responds to a selection measure.

the psychological conditions under which a job candidate responds to a selection measure.

the supervisor who scores a selection measure.

the physical conditions under which a selection measure is administered. (this was wrong)
