A researcher develops an aptitude test to predict entry level nursing students' probability of graduating successfully from a 4-year nursing school. The dropout rate is 25%. Which of the following is true about predictive evidence of validity?
A) An r of .9 would suggest that predictive evidence is high
B) The criterion variable will have more participants than the predictor variable
C) Entry-level students can be compared concurrently with a group of graduating students
D) a and b

Question

Quizplus · Accepted Answer

In predictive evidence of validity, a high correlation coefficient (r) between the test scores and later outcomes (such as graduation) indicates strong validity. An r of .9 is considered very high, indicating strong predictive evidence of validity. Therefore, option A is correct. Option B is incorrect, as the number of participants in the predictor and criterion variables does not affect the validity of predictive evidence. Option C is also incorrect, as the study design for predictive evidence involves administering the predictor test to a group of entry-level students and gathering data on their later outcomes (graduation) after a specific time period, rather than concurrently comparing entry-level students with graduating students. Option D is partially correct but does not explain the logic and reasoning behind the choices.
