Activity #7- Law Firm Example

Mean $60,000; Median $22,000; Mode $22,000

If a recruiter was trying to persuade a clerk tocome work for the law firm, he/she could claim that the average (mean) salary was $60,000. This would lure unsuspecting clerks to come to ajob which only pays $22,000. By the time they found out how little it paid, maybe all the high paying jobs would be taken and the clerk wouldbe stuck in the $22,000 job.
