Formulae.. *BANG*
Arg. I'm in my university library, with a pounding headache. I have a Biometrics (think Statistics for biology students) project due for Friday and Ive just finished all the statistics work I need to do for it.
Two-Sample T-Test and CI: wt_int_plac, wt_fin_plac
Two-sample T for wt_int_plac vs wt_fin_plac
N Mean StDev SE Mean
wt_int_plac 20 63.24 2.63 0.59
wt_fin_plac 20 63.69 2.72 0.61
Difference = mu (wt_int_plac) - mu (wt_fin_plac)
Estimate for difference: -0.446538
95% CI for difference: (-2.160168, 1.267091)
T-Test of difference = 0 (vs not =): T-Value = -0.53 P-Value = 0.601 DF = 37
How am I even supposed to understand what this means??? Unfortunately, I do, with the help of my Biometrics lecture notes. But GAWD, does it look unappealling.
I'm going to rest my exploded head for half an hour before I have to go show off a poster about cheetahs and inbreeding I spent all yesterday making..
GOOD GOD I WANT TO DIE.
Edit: I sent my work to myself so I could work on it at home (the statistics bit requires a computer program I can only access from uni) after the poster thing, which went well. However, once I got back home, it turned out that I'd done some of the maths wrong. Not fatally wrong, just some data flipped the wrong way, simple stuff. BUT ARG! Of course THAT meant I couldn't do what I needed to do at home, and I'll have to go back into uni and sort the whole lot out. On the plus side, the time I should have spent doing this, I used to write three essays instead...
