A Business Researcher Has to Decide Which of Three Employees

Essay

A business researcher has to decide which of three employees should be placed in a particular job that requires a high level of perceptual-motor coordination. All three employees have taken tests of perceptual-motor coordination, but each took a different test.
Employee A scored 15 on a test with a mean of 10 and a standard deviation of 2.
Employee B scored 350 on a test with a mean of 300 and a standard deviation of 40.
Employee C scored 108 on a test with a mean of 100 and a standard deviation of 16.
On all three tests, higher scores mean greater coordination.
Which employee has the best perceptual-motor coordination?
Explain your answer to someone who has never had a course in statistics.
