How do you calculate percentage error for equipment?
Look on the equipment for where it says the plus or minus figure for accuracy (for a burette it is usually + and _ 0.1cm3) divide this by the amount you measured , times 100 to make it a percentage. ---- ---- Percentage Error = Maximum Error / Measured Value X 100 For example. Maximum Error for the following apparatus are: Balance = +/- 0.01 Pippette = +/- 0.1 And the Measured value for each are: Balance = 0.15 Pippette = 25 Then...the percentage error is: Balance percentage error = 0.01 / 0.15 X 100 = 66.66% Pippette percentage error = 0.1 / 25 X 100 = 0.3% You can now also work out your maximum total error. Maximum total Percentage error = Balance Percentage error + Pippette Percentage error Maximum total percentage error = 66.66 + 0.4 = 67.06%
