Standard Deviation - probably not
One of the SGs says that we probably won't be required to calculate a standard deviation. Why the ambiguity?

Re: Standard Deviation - probably not
Hey J,
Because we've never seen a question that does it. However, the GRE still always mentions it. (For example, I believe they do give the equation in the Official Guide, as if it were worth knowing.) I tell my students they don't need to learn it, and I've yet to have someone come back and tell me they had a problem.
