   Aug 27, 2020 · A propagation of uncertainty allows us to estimate the uncertainty in a result from the uncertainties in the measurements used to calculate that result. For the equations in this section we represent the result with the symbol R, and we represent the measurements with the symbols A, B, and C.

   When you do quantitative experiments (those that require you to measure a quantity), you will have to calculate the total apparatus error from the sum of the apparatus error for each piece of equipment you use to make a measurement. Apparatus error for each piece of equipment = 100 x margin of error quantity measured.

   What is the difference between apparatus error and experimental error?

   • The experimental error (1.49%) is greater than the apparatus error (1.16%) meaning that the results are inaccurate. Find the mass of a clean, dry weighing bottle (high precision balance). All masses should be recorded in a table. Measure out the approximate mass of sample (low precision balance).
