The OG in its 6th chapter beginning states about Data Sufficiency questions that the questions will be from Arithmetic, Elementary Algebra and Commonly known concepts of geometry.

Are we supposed to infer from this that concepts like probability, sequences, exponents, statistics et al will not be used in any question on the official test? From what I've seen in practice sets, this definitely is not the ambiance of DS questions.

Please comment on how I can construe this statement.

Rahul

You're misinterpreting that statement. The GMAT question designers consider topics like sequences and probability to belong to 'Arithmetic' and 'Elementary Algebra'. Anything you can see tested in Problem Solving you can also see tested in Data Sufficiency, and if you want to get some idea of the scope of the test, you should work through the Official Guide.

I have the OG before me and that is what I referred when I posted the excerpt.

But I'd tend to disagree with the interpretation that Algebra covers topics like Probability, statistics and the like.

I do not have any problem if the DS questions cover the same areas as the Problem solving or Word problems. But the guide definitely needs to expand its ambit when mentioning the coverage.

If possible, can you pin-point me to the location in the OG where Algebra is said to be including these other areas (or I can content on the lines you mention)? I am concerned that I may have missed reading a paragraph or two.

Rahul:
Please be cautious about where you are posting your questions. All mathematical discussions' threads like this one should be created in the main math forum.
http://gmatclub.com/forum/gmat-math-questions-and-intellectual-discussions-7/

Only valid Problem Solving(PS) questions, with all given options preferably, should be posted in the PS Sub-forum.
http://gmatclub.com/forum/gmat-problem-solving-ps-140/

Only valid Data Sufficiency(DS) questions should be posted in the DS Sub-forum.
http://gmatclub.com/forum/gmat-data-sufficiency-ds-141/

Cooperation appreciated.

Moving this topic to main math forum.
