Hey guys I have a problem with calculating% error..
So when you use the formula % error = maximum error / quantity measured x 100%, say I have a measuring cylinder graduated in a 1cm3 division, the maximum error is +- 0.5cm3 right? So when substituting it into the equation, is the figure I put in for maximum error 0.5cm3 or 1cm3? Do you have to double it because the 0.5cm3 error could go either way? I'm soooo confused
Ive seen examples where its doubled and other examples where it isn't, what am I missing?
