I have a test that accurately predicts who will learn statics quickly. My test has
a. predictive validity but not reliability
b. content validity but not predicitive validity
c. predictive valisity and reliability d. neither validity nor reliability
To determine the answer, we need to understand the concepts of predictive validity and reliability.
Predictive validity refers to the extent to which a test can accurately predict future outcomes or criteria. In this case, the test accurately predicts who will learn statics quickly.
Reliability, on the other hand, refers to the consistency and stability of the test's results. A reliable test should yield similar results if administered multiple times to the same individuals or group.
Now, based on the given information, if the test accurately predicts who will learn statics quickly, it indicates that the test has predictive validity. However, there is no mention of reliability.
Therefore, the correct answer is:
a. predictive validity but not reliability
