Propagation of Error


The error, f, in a final result, F, derives from the error in each measurement or number (x, y,...) used to get that result. The error in a result, Ff, for F = f(x,y,...) is found from:

f = (dF/dx) ex + (dF/dy) ey + ...

where dF/dx is the partial derivative of F with respect to x, and ex is the uncertainty in x.
