Card 88 / 104: A researcher creates a new motoric test in which clients throw a baseball at a target 40 feet away. Each client is given 100 throws, and the mean on the test is 50. (In other words, out of 100 throws the mean number of times the client will hit the target is 50 times.) Sam took the test and hit the target just two times out of the 100 throws allowed. Jeff, on the other hand, hit the target an amazing 92 out of 100 trials. Using the concept of statistical regression toward the mean the research would predict that
A)
Sam and Jeff’s scores will stay about the same if they take the test again
B)
Sam and Jeff will both score over 95 next time
C)
Sam’s score will increase while Jeff’s will go down.
D)
Sam will beat Jeff if they both are tested again.
Answer:
C) Sam’s score will increase while Jeff’s will go down.
