College football recruiting services rank incoming players on a scale of 1-star (not a highly sought-after prospect) to 5-star (considered to be the best players). Recently a service attempted to validate its rankings by assigning star ratings to players upon completion of their careers to determine the accuracy of the initial rankings. The survey averaged the post-career ratings of each player and found that 5-star players’ final average was 4.46, compared with 3.98 for 4-stars and 3.11 for 3-stars. This suggests that the rankings services do not effectively judge high-end talent as well as they judge players in the middle of the range.

Which of the following identifies a problem with the service’s attempt to validate its rankings?

(A) Players at certain positions might be harder to judge at a younger age than players at other positions
(B) A five-star scale does not allow the most elite players to overperform their initial ranking
(C) Players may change positions over their careers and be judged at multiple different positions
(D) Some players transfer to different schools and therefore need to change their playing styles
(E) Because of differences in strength training programs at different schools, players may develop at different rates

Official Explanation:

Answer is B

This problem demonstrates a type of data flaw that you might not expect – which is exactly what the author of a hard question wants, for you to accept a faulty conclusion because you did not critically examine the data. What’s the flaw here? In a five-point scale, a predicted ‘4’ has multiple outcomes: a 5 (exceeding expectations and bringing the group average up), a 4 (meeting expectations, keeping the average the same), or a 3 or below (underperforming the prediction, bringing the average down). But a predicted ‘5’ can only live up to expectations – it cannot exceed them. Anything other than a 5 brings the expected average down. So while the experts’ misevaluations of a 4-star prospect might be balanced out by some 5s to counter 3s, their evaluations of a 5-star prospect all count in the same downward direction. Choice B exposes this flaw – the experts may have missed just as often with 3 and 4 star players, but because they could miss on either side of the predicted value the average is close to what they predicted.For your study, this is important – especially with the Integrated Reasoning section included, the GMAT will feature plenty of problems in which statistics are used improperly, to draw invalid conclusions. Be skeptical of statistics and train yourself to look for data flaws, both on the GMAT and in business in general.

Definitely B. B talks about highly rated 5 star players and says they cannot over perform their initial ranking. The last statement of stimulus says the same.

I think B is the best answer. The rest all are not in scope. We are only worried about why there is a deviation for 5 star rating and B gives the best answer supporting that.

Answer is E
A, B C &D are not relevant as the system compares initial and final scores and not when the athletes peak in their careers.

College football recruiting services rank incoming players on a scale of 1-star (not a highly sought-after prospect) to 5-star (considered to be the best players). Recently a service attempted to validate its rankings by assigning star ratings to players upon completion of their careers to determine the accuracy of the initial rankings. The survey averaged the post-career ratings of each player and found that 5-star players’ final average was 4.46, compared with 3.98 for 4-stars and 3.11 for 3-stars. This suggests that the rankings services do not effectively judge high-end talent as well as they judge players in the middle of the range.

Which of the following identifies a problem with the service’s attempt to validate its rankings?

(A) Players at certain positions might be harder to judge at a younger age than players at other positions
(B) A five-star scale does not allow the most elite players to overperform their initial ranking
(C) Players may change positions over their careers and be judged at multiple different positions
(D) Some players transfer to different schools and therefore need to change their playing styles
(E) Because of differences in strength training programs at different schools, players may develop at different rates

Ans is (B).

Explaination:
A 5-star player can be rated at a lower star rating later on but never above a 5-star rating.
A 4-star rated player can be assigned 3 of lower star ratings (viz. 1-star, 2-star & 3-star) but only one star rating above what it was originally judged (viz. only 5-star)
