Marcia knew the importance of testing candidates before hiring them, but 40% of the employees who successfully passed the employment test later performed poorly on the job. marcia's employment test lackeda) applicability.
b) interpretability.
c) reliability.
d) validity.

D) validity.

Explanation:

Validity of a test occurs when the test actual test what it is intended to test. If Marcia:s test was testing exactly what it was supposed to test it should have not successfully passed 40% people who later seemed to perform poorly when they were put into real work.

This means this people should have failed the test if it really did measure their work capability as it was supposed to.

Instead it passed the people who should have failed since they are not good hence didn't measure what was intended then it lacks validity.
