Where's the best place to begin for someone who has always been fascinated by statistics and is strong in math but was a liberal arts major in undergrad and has a professional degree in a non-quantitative field? I want to make sure that (1) this is something I really want to do, and (2) I have the aptitude to do it. I got a 5 on the AP Statistics exam way back when, but I imagine that’s tantamount to a Statistics for Non-Majors course at best. Would it be sensible to start by taking a survey level course at the local community college or State U? If that goes smoothly, what next? Would an undergraduate certificate in statistics be enough to apply to reputable PhD programs? My college-level math ended with business calculus (in which I got an A+, FWIW), so I know I have a ways to go on the quantitative prerequisites alone.
