Title: Uncertainty calculations
Post by: ernest1039401 on June 23, 2018, 06:30:51 AM

Please *delete me* I have been repeatedly attempting to calculate the uncertainty for the average initial rate of my experiment (ml of oxygen produced per second). For my experiment, I have calculated the percentage uncertainty of each of my 3 trials by adding the percentage uncertainties of time and volume, but I have no idea how to use these results to calculate the percentage uncertainty for the average intial rate! Advice would be very much appreciated! Thanks in advance!

I think you should give more information about your experiment with numbers and your calculation. So is it virual and nobody can check is it ok or not what you did so far.
