For each of five models of computerModels V through Zthe table shows

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

Hi Yashik, how do you know that Test A is on the top of the list?

When I read the question, it seems to just imply that there are 3 tests. But no indication of the significance of each test.

i still dont understand the solution

2 images are missing i believe. those that arrange the model as per performance on tests B and C.

Hey guys!
No info is missing. Today I took a mock EA test and this question was there...
I still don't understand how that question can be solved.

I think this is a pretty poorly formatted Q. I figured that the trick while sorting is to click the alphabet that represents the test (A, B or C), instead of the arrows next to it - that action formats the table to give us the required organization quite simply. On doing so, you will get a table that clearly shows col A sorted in descending order and B and C in ascending order, thus giving us the right answer:
Greater scores are better for Test A
Greater scores are worse for Tests B & C

Don't be too hard on yourself if you didn't get it. I do think that it's a poorly formatted Q.

Good luck!

Thank you for shedding light on the solution. Could you share why it can't be the other way round?
e.g. Greater scores are worse for Test A; Greater scores are better for Tests B & C

Could you please advise on this question?

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.

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..

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.

Please see the attached photos, which show all ways the data could be cut. Depending on the number of times you click the filters at the top, it changes what answer would be..

Now the table can be sorted both by ascending order and by descending order.
The question indicates that there can only be one order when we sort each test in order of performance.

The function of this table needs to be fixed.

­Something is missing ! 

The sorting is causing the issue here, as in MSR Questions the tables are not sorted, but in Table Analysis questions they are.

Here are the actual images
Test A: https://prnt.sc/qNy3iMmMgEm7
Test B: https://prnt.sc/-PWQHKmpwlZz
Test C: https://prnt.sc/LOuPw5ubYDQ1

Once you see the correct sorting, the solution becomes quite obvious.

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

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.
