Review of Measurement Uncertainty
The existence of random error means that the standard deviation of many
measurements is the best indication of the uncertainty of one of those
measurements. This concept was applied e

Propagation of Uncertainty
Reporting measurements with uncertainties is simple, but what happens to the total
uncertainty if two measurements with individual uncertainties need to be
multiplied together? Each numb

Method using propagation of uncertainty rules
Round the uncertainty to one significant figure: u(A) = 0.08 m2
This tells you the number of decimal places you can confidently state the area A =
30.10 m
A = (30.10 0.08) m2
