3. Dr. Hofsted wants to assess the validity of a new selection test. It is likely he will use performance appraisal information as a(n) to see if how people perform on the selection test predicts how they are doing on the job

predictor

Explanation:

For Dr.Hofstede to evaluate the validity or consequent effectiveness of his selection test, he would have to gather performance appraisal information from the tests taken on which he bases his predictions on whether these tests truly reflect the performance of people on the job. If for example people who score high on the test, perform well on the job, it would mean that the test effectively predicts job performance.

extraneous variable    

Explanation:  Predictor variables are used in research to measure how much an event affects another and how accurately this relationship can be predicted or guessed even before the dependent event occurs. An example is finding the relationship between sleeping three hours later than usual  and waking up late. The predictor variable here is the time you go to sleep and it can predict when you wake up.  

In essence it is the degree of risk/certainty associated with a variable event.
