a) Predictive validity
b) Content validity
c) Concurrent validity
d) Construct validity

Answer 1

Shoe size is not an effective predictor of success in college due to a lack of predictive validity, which is the ability of a test or measure to predict future performance.

Step-by-step explanation:

The question asks whether shoe size is an effective predictor of success in college, and the answer is that it lacks predictive validity. Predictive validity refers to the extent to which a score on a scale or test predicts future performance or outcomes. In the context of admissions, colleges traditionally use SAT or ACT scores because they are believed to have stronger predictive validity for college success, in terms of grades or retention, than unrelated factors like shoe size. However, the SAT's predictive validity itself has been called into question, with some studies suggesting that its ability to predict first-year GPA may be overestimated.

Despite these concerns, shoe size would lack any rational connection with college success, indicating a lack of predictive validity for academic performance.
