I'm finishing up my prerequisites before starting grad school in the fall. Statistics is one of my classes, and I'm finding it really hard to do everything I have to do for all 4 of my classes this summer. So my question is -- and I think a current grad student would have the most insight into this -- what is the truly important stuff that I'll need to know in statistics for grad school, assuming I might be writing a research paper?
Obviously there's the basic stuff like understanding a bell curve, and percentiles, etc., but what about stuff like probability computations?? I have to pass statistics, but at this point I don't think it makes sense to kill myself trying to learn everything in my statistics book. I have serious doubts that I'll need all of that information -- but at the same time I'm not sure what exactly I'll need to know.
