Welcome

I call this my Table Method. If you find my method useful, I would appreciate a voluntary contribution. Propagation of Error is a method for calculating the uncertainty of calculated variables that are functions of experimentally measured data. The method requires knowledge of:

• the uncertainties of the experimentally measured data
• the partial derivatives of the calculated variables with respect to the experimentally measured data

It is assumed that the uncertainties of the measured data are already known. The difficulty in using Propagation of Error lies in calculating the partial derivatives. My method finds the values of the partial derivatives easily and accurately. All you need is the spread sheet you already use.

• The first video provides background about and Propagation of Error and also shows a derivation.
• The second video explains my method and gives two examples. There are three spreadsheets accompanying the 2nd video.
  • Two spreadsheets show the examples used in the 2nd video.
  • The third spreadsheet shows examples of the accuracy of the method – comparing values of derivatives obtained using my Table Method with the analytical solutions.

I hope that you find my method useful and that you will make a donation.
