Question

Kumar Abhishek · Accepted Answer

Final Answer : D, Explanation :  Predictive validity refers to the ability of a test to predict future performance. Option D states that students who do well on the test also get good grades in school, which indicates that the IQ test has high predictive validity. Option A is incorrect because accurately guessing someone's score before taking the test is not necessarily a sign of predictive validity. Option B is not relevant to predictive validity but rather suggests test-retest reliability. Option C is incorrect because the mean and standard deviation may vary across different groups of people.
