Answer:
c. predictive validity
Explanation:
In research, the term predictive validity refers to the fact that a score in a test or the performance on a task is related to the performance in another test or task that is evaluated in the future after the first test. So, the first test/criterion will likely predict how the person will do in the second one.
In this example students take a college entrance exam and it's been observed that the ones who do well in them, do well in their first year of college. We can see that <u>the score in the entrance exam will likely predict how the students will do during their first year of college</u>. Therefore, these exams have predictive validity.
