How To Calculate Percentage Error In Physics

The difference between the actual and experimental value is always the absolute value of the difference. |Experimental-Actual|/Actualx100 so it doesn't matter how you subtract. 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 If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine.

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

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

or can the Mods just move it To calculate the percentage error for the apparatus you need to know the error margin for each piece of equipment. Excluded sections are 12.3*, 13.4, 15.3, 16.4, 17.4, 18.3, 18.4, 18.5, 19.4, 19.5, 20.3. *We learned about percent yield but excluded limiting and excess reagents.
