I'm trying to finish an assignment and I keep coming back to this annoying thing about systematic and random uncertainties.
If anyone knows anything that could possibly help I will be eternally grateful! It's driving me mad!
I've done a precipitation recording experiment, and I have the data, but they need 3 examples of uncertainties, at least 1 systematic and 1 random. The 3 uncertainties I thought of are:
Wind affecting the level of water that goes in the pot, which could mean that the levels are either reduced or increased, but you cannot measure it, so it's a random uncertainty.
Rain splashing off the funnel, so less water and systematic uncertainty as I could prevent it by placing something on top of the pot to ensure the splashes go back into the pot.
and the pot falling over, which would be less water and a systematic uncertainty as it is just one loss of water, not a constant loss.
I have no idea if any of that is right, and I'm so bored of doing web research and being even more confused!
Any advice you can give would be seriously helpful.
Thanks!

Can you pin down the definitions (for this context) for systematic and random uncertainties more precisely?
And if you are thinking of topping yourself, try to stay away from the ice cream van, eh?
:^p

Well they kind of assume that you should be sensible enough to prevent that happening in the first place and seeing as I used a tin can, the chances of that happening is fairly limited!
However my housemates did offer to take a leak in it, to give me something to write about!
I don't need any more uncertainties, I just need to know whether they are random or systematic - I have put what I think but I just want someone to tell me if I'm right, as I don't really understand the whole systematic/random differences. Like the spillage, I know it's just one spillage, but as I will never know the actual amount of the uncertainty, does that make it systematic or random? Also with the splashes & wind, I'm not really sure if they should be random or systematic, as they could really be stopped with the right equipment/technology.
