    How to choose between two uncertainty calculation method?

    Thank you ImaLooser for your explanation. I assume that the accuracies are independant. 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...

    How to choose between two uncertainty calculation method?

    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...

    How to evaluate an uncertainty involving an experimental correlation?

    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...

    How to evaluate an uncertainty involving an experimental correlation?

    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...

    How to evaluate an uncertainty involving an experimental correlation?

    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...
