Thank you very much. I understand now the difference.

Thank you ImaLooser for your explanation. I assume that the accuracies are independent. But I don't know if the accuracy of the intruments are standard deviation (I always think that they are the maximal error; I may be wrong). Actually, for a long time, I do not realize that the accuracy of an...

Hello, I have made an experimental work and I am ask to provide a formal experimental error analysis. I have a difficulty to choose the appropriate analysis way and would like to have some advices or explanations. I have measured a temperatures at the intlet (Ti) and outlet (To) of a heat...

Thank you both for your responses. Yes, I will try to well understand the calculations of Stephen Tashi. There is no critical decision that is going to be taken but I as a scientist, we usually need to evaluate the uncertainties of our measurements in order to evaluate the significance of our...

Thank you for the answer. Actually, I did not "care" about because I usually think "uncertainty" and nothing more. But now, I can find, you are right, the authors stated "standard deviation". Temperature sensor: as suggested in my first post, the accuracy of our thermocouple is 0.5°C and has to...

hello, Thank you to understand that this is not a homework! I have to evaluate the uncertainty of a measurement but the baseline is also with uncertainty (correlation). I would like to have some ideas or suggestions on the best way to evaluate the uncertainty. Here is the problem: We...
