Another favourite word today: stochastic. It's a word often used by scientists to explain variability in results or observations when there is no other credible explanation. Ie "I've no idea why the growth rates are different in the two locations. It must be due to stochastic effects". Once again, I'm not entirely sure why I like it, but I suspect it has to do with the fact that you can still sound like you know what is going on even though you don't.
sto·chas·tic ( P ) adj.
