Question

For each of five models of computer—Models V through Z—the table shows the model's scores on each of three performance tests (Tests A, B, and C). The models are listed in order of better performance, with the best performances at the top.

  Test B  
  Test C  
 
   X  
 10068 
 87 
 68 
 
   W

 104 
 82 
 
   Y  
 8369 
 121 
 103 
 
   Z  
 7667 
 130 
 93 
 
   V  
 6970 
 119 
 87

For each of the following performance tests, select  Greater scores are better  if greater numerical scores on that performance test indicate better performance. Otherwise, select  Greater scores are worse .

KarishmaB · Accepted Answer

The actual table will be dynamic and you will be able to sort based on the test A, B or C. The best performance would be at the top. If it is the greatest numerical value, then you select "Greater scores are better" for that test. If the smallest score is at the top, then you select "Greater scores are worse".

It doesn't matter how many times you press the button to sort based on a certain test. For A, it should always give the greatest score at the top and for B and C it should always give the least score at the top.

yashikaaggarwal · Answer

In The Following Table,
Test scores are in descending order, from best model to degrading test model.

Where The higher the score, The better is the model. 
Test A is on the top of list. 
So, the test where the greater the score the better the test is Test A.

In Test B and C, X is on the top of the list and didn't score greater in both the test, so Test B and C represent that the greater score is the lesser the quality of the model.

Hence,
Test A: Greater scores are better
Test B: Greater scores are worse
Test C: Greater scores are worse

Could you please advise on this question?

chetan2u · Answer

The questions requires you to check the test B and C too, a situation that cannot be done here as the table is just a picture and not the actual one.

In the picture, A is sorted out and the numbers are in descending order, so higher the score, higher the position.

But in B and C, I believe when you press the button from top to bottom, the scores will be in ascending order that is smaller to bigger. This would then mean smaller the score, higher the position.

This is what I believe the question should have been. But the actual table can only tell us the exact meaning.

mba757 · Answer

Hi thank you for your response chetan2u!

The strange thing with this problem is that you can filter on columns A, B, and C and depending on whether you click it once or twice, it will either make the values descending or ascending. i.e., you can cut the data in different ways for A, B, and C, so in a way you can argue the opposite too..

chetan2u · Answer

An upside triangle should give us higher to lower, so logically under test B, I believe the upside triangle should give you values in ascending order meaning least value is on top. 
But one can be sure only if the details of test B and C when in some order is given.

It is problematic the way it is given.

Can you please explain the logic behind? Select everything in reserve order. It's like kind of correlation question.

KarishmaB · Answer

It isn't a correlation question though it makes sense that one would think that it could be assuming if one model performs well on one test, it will perform well on others too. But that is too much of an assumption. A product could be rated very differently on different parameters.

The cause of the entire confusion is the format of the table. I believe that in the actual question in GMAT Prep, the table can be sorted using a test in only one way - either ascending or descending - not both as is present here.

So if you sort the table by Test A, you will get the data in descending order only and since best performances are at the top, greater score in A will mean better performance. You will not be able to sort the data in ascending order on Test A. 
The reverse will be true for tests B and C.

The question would be actually extremely simple when put in the correct format.

Best performers at the top - so does this mean that the order of performance is: x>w>y>z>v?

Given:   
 
 A table listing five computer models (V through Z) and their scores on Test A, Test B, and Test C. 
 The models are already arranged in order of better overall performance, with the best-performing model at the top.

To Find:  For each test, determine whether greater numerical scores indicate better performance or greater scores indicate worse performance.

Solution:  
 Since the models are already ranked from best (top) to worst (bottom), we compare how scores change as we move down the table.

Statement 1 : Test A 
 
  No new sorting needed since models are already ranked by performance.  
  Observe Test A scores from top to bottom:  10068 - 9675 - 8369 - 7667 - 6970  
 
  Scores decrease as performance worsens.   
 
  Thus, higher Test A scores correspond to better performance.

We mark "Greater scores are better"

Statement 2 : Test B 
 
  No new sorting needed.  
  Observe Test B scores from top to bottom:  87 - 104 - 121 - 130 - 119  
 
  Scores generally increase as performance worsens.   
 
  Thus, higher Test B scores correspond to worse performance.

We mark "Greater scores are worse"

Statement 3 : Test C 
 
  No new sorting needed.  
  Observe Test C scores from top to bottom:  68 - 82 - 103 - 93 - 87  
 
  The best-performing model has the lowest Test C score.  
  Higher values tend to appear lower in the ranking.   
 
  Thus, higher Test C scores correspond to worse performance.

We mark "Greater scores are worse"

Correct Answer: Greater scores are better, Greater scores are worse, Greater scores are worse

Hi arushi118,

Yes, you've got the ranking exactly right! The table tells us the models are listed best to worst from top to bottom, so the overall performance order is X > W > Y > Z > V.

Now, the key question is: for each test, do the scores go UP or DOWN as we move from the best model (X) to the worst model (V)?

Test A:  X =  10068 , W =  9675 , Y =  8369 , Z =  7667 , V =  6970 . Scores DECREASE as performance gets worse. This means higher scores = better performance. So:   Greater scores are better.

Test B:  X =  87 , W =  104 , Y =  121 , Z =  130 , V =  119 . Scores generally INCREASE as performance gets worse. The best model (X) has the LOWEST score of  87 . This means higher scores = worse performance. So:   Greater scores are worse.

Test C:  X =  68 , W =  82 , Y =  103 , Z =  93 , V =  87 . Again, scores generally INCREASE as performance gets worse. The best model (X) has the LOWEST score of  68 . So:   Greater scores are worse.

Key Insight:   You might notice that Tests B and C don't perfectly increase from top to bottom (for example, V has  119  on Test B, which is less than Z's  130 ).  That's okay — don't fall into the trap of expecting a perfect sequence.  The question says the models are ranked by OVERALL performance, not by any single test. The general trend is what matters, and the trend clearly shows that better-performing models have lower scores on Tests B and C.

Advait01 · Answer

Where The higher the score, The better is the model.
Test A is on the top of list.
So, the test where the greater the score the better the test is Test A.

In Test B and C, X is on the top of the list and didn't score greater in both the test, so Test B and C represent that the greater score is the lesser the quality of the model.

Hence,
Test A: Greater scores are better
Test B: Greater scores are worse
Test C: Greater scores are worse
