Question

Using a 10-point scale, two managers independently rate the performance of the same five salespeople. The ratings appear below. Higher scores indicate better performance.

Salesperson Manger 1 (x) Manager 2 (Y)

J 9 4

K 4 8

L 5 4

M 3 8

N 4 6

c. Assuming both managers are supposed to use the same objective criteria (like sales, absences, etc.) to rate the salespeople, state whether you find the direction of the relationship sensible or not, and (briefly) explain your answer.

*a scatterplot was drawn

Answer 1

Solution:

Given that, two managers independently rate the performance of the same five salespeople. We have to state whether the direction of the relationship sensible or not,

Scatterplot 8 Rating by Manager 2 o 9 5 4 3 4 5 6 7 8 9 Rating by Manager 1

From the scatterplot, we see that there is a inverse relationship between the ratings given by the two managers, since both managers are supposed to use the same objective criteria (like sales, absences, etc.) to rate the salespeople, so the direction of the relationship is not sensible as one manager give high ratings to a salespersons while another manager give low rating to the same salesperson.
