Shuddering with SDs

I'm going to muse on and off this weekend, since I'm stuck in the hospital for 48 hours, so I've certainly got time to kill...
I remember being quite good at math when I was a kid. I even participated in math contests in high school, I was that stereotypically nerdy.
But seriously, since I finished those mandatory first year math courses in undergrad, I have barely done anything involving a calculator for years - I don't even do my own taxes!
So, suffice it to say, when I was told I have to have a mandatory undergraduate statistics course done before the end of May this year, I had a small frisson up my spine; I hadn't done any sort of math for over a decade! You'd think a modern, intelligent woman like myself could handle a stupid little undergrad course, but I'd been moaning and groaning in anticipation of horrid, complicated formulas that would make me go cross-eyed and even more myopic. And it's true; I'm still moaning and groaning, though through only the first one-sixth of the course, it hasn't been as horribly awful as I was afraid of. Sure, it's work, but I have to keep reminding myself that if some 19 year old pre-med keener can do this course, then so can I.
