Question
I have designed a new intelligence test and want to make sure that it is a good test. So had students.take the test before entering university four years ago. Now I calculate the correlations between test scores and four-year GPAs. I am testing for a. content validity b. internal consistency c. construct validity d. criterion validity e. interjudge reliability

The correct answer is **d. criterion validity**.Here's why:* **Criterion validity** assesses how well a test predicts an outcome (the criterion). In this case, the test scores are being compared to four-year GPAs (the outcome/criterion) to see if the test accurately predicts academic performance. A strong correlation would suggest good criterion validity.Let's look at why the other options are incorrect:* **Content validity:** This refers to whether a test covers all aspects of the construct it's supposed to measure. This scenario doesn't address the comprehensiveness of the test's content.* **Internal consistency:** This measures how well different parts of a test correlate with each other, indicating whether they are measuring the same construct. This scenario doesn't involve comparing different parts of the test.* **Construct validity:** This is a broader concept that encompasses criterion validity. It examines whether the test actually measures the underlying theoretical construct it's designed to measure. While related, this scenario specifically focuses on the predictive ability (criterion validity) of the test.* **Interjudge reliability:** This refers to the agreement between different raters or scorers. This scenario doesn't involve multiple scorers evaluating the same test.
