Uncertainty andEquipment Error by Chris Paine Bioknowledgy 2. Absolute uncertainty and recording data When you record measurements you should also record the (absolute) uncertainty associated with the measurement The uncertainty reflects greatest precision, i.e. the smallest unit to which a measurement can be made. This method of quoting uncertainty is called least count 3. Absolute uncertainty and recording data For example measuring a length: We measure a length

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 = percentage error of 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% 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% Minor edit? Save Cancel 56 people found this useful Was this a

Units Using algebra Presenting data:... Proportions Geometry Uncertainty and percentage errors Experimental data is never exact. There is always an element of uncertainty in the data due to: the precision of the equipment; imperfections in the experimental procedure; and judgements made by the operators. Experimental uncertainties are those which cannot be quantified and often arise from making a judgement. For example, judging the end point of a titration by a colour change.Quantitative uncertainty is usually expressed as a percentage error. This value is calculated from the accuracy of the apparatus and by taking readings from the scientifc apparatus. © ShutterstockPercentage errors can be calculated using the expression:% error = [
