Bioequivalence and Bioavailability Forum

Dear all,

thanks all for your input. I am sorry I am so out of reach of common didactics. The best I could do, and best I still can do:

SD: A measure of how much the observations are scattered.
SE: A measure of how much uncertainty we have on our estimated quantity.

Somehow I thought you guys would have like a mental image of it which you could share. That is how I get my head around things that are hard to grasp. Like e.g. the Hydrogen atom: A football with a pingpong ball flying around it in circles of discrete radia. Other atoms: Still a football of sorts, possibly larger than the previous one, and now with beaucoup de little balls flying here and there. SD in my head easily goes as a dartboard with arrows sitting scattered around the bull's eye. And so forth.
Somehow I am missing such a mental picture for an SE, I hope you see what I mean.
I have the same mental blockade about entropy by the way - people talk of disorder and chaos and information content to describe it, and all that is fancy, but I am only observing a blue screen of death, mentally. Fortunately, entropy hasn't found its way into BE yet
