we might measure the length, height, width, and mass of the block, and then calculate density according to the error propagation example equation Each of the measured quantities has an error associated with error propagation chemistry it ---- and these errors will be carried through in some way to the error in our answer, propagation of uncertainty calculator . Writing the equation above in a more general form, we have: The change in for a small error in (e.g.) M is approximated by where is the partial derivative http://www.ncbi.nlm.nih.gov/pubmed/16506991 of with respect to . In the worst-case scenario, all of the individual errors would act together to maximize the error in . In this case, the total error would be given by If the individual errors are independent of each other (i.e., if the size of one error is not related in any way to the size of the https://courses.cit.cornell.edu/virtual_lab/LabZero/Propagation_of_Error.shtml others), some of the errors in will cancel each other, and the error in will be smaller than shown above. For independent errors, statistical analysis shows that a good estimate for the error in is given by Differentiating the density formula, we obtain the following partial derivatives: Substituting these into the formula for , Dividing by to obtain the fractional or relative error, This gives us quite a simple relationship between the fractional error in the density and the fractional errors in . It may be useful to note that, in the equation above, a large error in one quantity will drown out the errors in the other quantities, and they may safely be ignored. For example, if the error in the height is 10% and the error in the other measurements is 1%, the error in the density is 10.15%, only 0.15% higher than the error in the height alone.
