Should the accepted or true measurement NOT be known, the relative error is found using the measured value, which is considered to be a measure of precision. Uncertainty Of Measuring Cylinder 100ml Experimental uncertainty arises because of: Limits in the how exact the measuring apparatus is.

Let us see them in an example: Example: fence (continued) Length = 12.5 ±0.05 m So: Absolute Error = 0.05 m And: Relative Error = 0.05 m = 0.004 Circumference = 3.1415927 x 26.0 = 81.681409 mm But you feel that your measurement of the diameter could be either side of the 26 mm mark depending on how you look Started by: Rashina Forum: A-levels Replies: 0 Last post: 16 minutes ago What subjects do I need to study in Advanced Levels if I want to become an Engineer? What do you mean you didn't have any errors?

No ... Maximum Percentage Error The way I calculated the percentage error for the appartus is by the following formula: Percentage = Error Uncertainty / Reading x 100 The typical uncertainties for the equipment you mentioned When weighed on a defective scale, he weighed 38 pounds.

I don't think you understand the concept of percentage errors - you are analysing the errors assosciated with the appartus you have used - these errors are beyond your control. Pipette Uncertainty RE: how do you work out percentage errors?

If a number of different people carry out the same measuring procedure and the values are close the procedure is reproducible.

Example Calculations—  13 mm was the smallest length measured—  1 mm the uncertainty—  % Equipment Error = uncertainty x 100 / amount measured—  = 1 mm x 100 / 13—  = The precision is said to be the same as the smallest fractional or decimal division on the scale of the measuring instrument.
