I agree now. Search Google and see people use both.
But Barron GMAT goes for correlate with. So I guess it should be right????
This reminds me of: relate to vs. relate with, btw

I tried googling and went through couple of online dictionaries. At most of the place "correlated to" or "to correlated" is used. However, google clearly shows both, "correlated to" and "correlated with" are used evenly. So, as mentioned in Barron GMAT, is "correlated with" rule of thumb? or is it context dependent?

Most of times , Idiom depends on the usage..there are not thumb rules for all idioms....

Pls post the sentence and let us all see..which fits the bill

Here is the sentence in Barron Diagnostic Test

On the African continent, the incidence of vitamin deficiencies correlates positively with the level of solar radiation

Be careful! Correlate here is a verb, not adjective <be correlated with>

Corelate with looks good..but can you post the entire question to whether there is any better option

On the African continent, the incidence of vitamin deficiencies correlates positively with the level of solar radiation
A. ...
B. deficiencies correlate positively with
C. deficiencies, correlate positively with,
D. deficiencies correlate positively to
E. deficiencies correlates positvely to

A. ...
B. deficiencies correlate positively with
C. deficiencies, correlate positively with,
D. deficiencies correlate positively to
E. deficiencies correlates positvely to

It looks E

"The incidence" is singular and hence correlated

OA is A

I'm lost on this one too. Barron said "deficiencies correlates positively with." Its explanation on this answer is vague.

IMO corelates with is correct here.

Because, the sentence correlates the viatmin deficency with Sloar radition.
Comparing the effect of one on the other. hence "correlates with" sounds good.

IMO, A.

incidence of ... correlates with..

the proper idiom is “correlate … with” rather than “correlate … to.”

It is "correlate with". Here is another question from MGMAT that tests almost identically:

According to a recent study by the Occupational Safety and Health Administration, the incidence of reported neck and back pain correlate positively to the amount of time spent in sitting positions at work.

correlate positively to

are correlated positively to

correlate positively with

correlates positively to

correlates positively with

OA is E...

Frequently, the etymological root of the word gives some clues. Cor- in 'correlate' comes from the Latin word/prefix cum or con-, meaning 'with.' Granted this doesn't always apply, but in an ambiguous phrase, it's frequently better to match up with the Latin/Greek root.
