Altoneicia conducts a validation study and finds r=.55. She obtains a second sample and when she validates the measure this time, she finds r=.06. This notable drop between her first sample and her second sample suggests that:

A) her measure does not apply well to different samples and probably should not be used.
B) her measure discriminates against a protected class and probably should not be used.
C) her measure demonstrates very little shrinkage and is ready to use to select employees.
D) her measure demonstrates validity generalization and is ready to use to select employees.

Ans: A) her measure does not apply well to different samples and probably should not be used.
