Hello,
Here it says "the shrumeroo ratio that STRONGLY CORRELATES to the level of success that such corporations have in creating a high ROI on investments in marketing"
Does 'Strongly correlates' mean strong positive correlation?

Hi Ankit!
Great catch! And honestly, this is just one of a
TON OF MASSIVE LOGICAL AND QUALITY ISSUES with this problem. Happy to list out all of the things wrong, but just know that
this question DOES NOT have any verifiable right answers for either column.
As I try to reinforce - studying from BAD materials is worse than not studying at all, so please please please throw this question out of your mind completely!
First, let's talk the minor stuff that makes this so clearly not GMAT-level quality. So this is the grammar and style stuff (in the order they appear):
"ROI on investments..." = the OI in the acronym literally means "on investments" so you don't say "the return on investments on investments."
"shared characteristics in common" = redundant, if they're shared, they're in common.
"marketing corporations that do a large amount of direct marketing and high employee turnover" = not parallel. Marketing corps THAT DO ... and HIGH? It should be "marketing corporations that DS a large amount of direct marketing and HAVE high employee turnover"
"which of the following characteristics of a corporation is.... and which ones are typically associated" = each column is a SINGLE characteristic, so saying which ONES for the second column doesn't make sense. Should be "which IS"
And even the answer choices have periods when none are complete sentences (also something the real test wouldn't do).
Okay, annoying, but let's say we decide to ignore the poor editing cause we can live with that or at least sortof overlook it. Let's talk about the wildly problematic and even downright WRONG elements, in the order they appear again in the argument itself.
"a fictitious type of metric called the shrumeroo ratio." = It's a "ratio" so the writers would spell out what it is a ratio OF. If it was just a metric without then calling it a ratio (maybe call it a score), then maybe okay. But as is, the GMAT isn't going to call something a ratio and not explicitly tell you what it's the ratio of. And honestly, even if they make up stuff, they give far more explanation about what it is or how it's derived than this!
"have come up with a new metric called the shrumeroo ratio that strongly correlates to the level of success that such corporations have" = here is the point that you made. Strongly correlates doesn't mean anything without more information. They could say that "a high shrumeroo rating strongly correlates to a high level..." or they could say that it has a strong positive correlation to indicate that increasing one increases the other. So any answer choice that expects you to just "know" the correlated relationship is going to be a problem. The real writers and editors would be clear about this.
"employee to revenue" and "expense to employee" ratio is sloppier language that the writers would use. They would mathematically spell that out (# of employees divided by ....). Not to mention that these should be hyphenated.
Finally, the nail in the coffin are the two answer choices that the writer claims are "correct."
Correlates to LOW ratio: Low ROIs.- Nope, as written we CANNOT infer this based on what we talked about above. A strong correlation doesn't tell me if they are positively or negatively correlated without more info.
Correlates to HIGH ratio: Overall expenses per employee that are lower than the average for the country.- Nope, as written we CANNOT infer this either. The sentence in question is the following:
Quote:
They have found that such corporations will have a high employee to revenue ratio but a low expense to employee ratio as well as employee salaries that are lower than the national average. The structure of this sentence is as follows: Corps will have a (high X but a low Y) as well as (Z). From the structure of this sentence, GMAT writers would have made everything parallel (which it isn't). The Z element doesn't start with high or low (or a modifier), it starts with the noun. But, here comes the real issue. The modifier "that are LOWER than the national average" ONLY applies to the employee salaries. It would make NO sense to apply this relative pronoun modifier randomly past Z to include Y when it wouldn't include the X that Y is locked in with. Therefore NO, we have no idea if the overall expenses per employee are lower than the average, only that they are LOW.
So again, nice catch - time to ignore this problem!
