Calculate the comprehensive error of the measurement

Thread Content

In a certain measurement, the errors of the three 1-gram weights used were X1 = 2 μg, X2 = 4.5 μg, and X3 = –3 μg. What is the overall error for this measurement? How is this calculated?

Mm-hmm, so it’s all added together, right?

Is it (X1+X2+X3)/3=1.17 or (X1+X2+X3)=3.5?
