If the same person obtains these close values, then the experimental procedure is repeatable. 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.

Now try calculating the following percentage uncertainties... 1.00 g on a 2 decimal place balance 10.00 g on a 2 decimal place balance 1.00 g on a 3 decimal place balance Truong-Son N. How To Calculate Percentage Error In Physics Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value. Can Percent Error Be Negative For example, for a thermometer reading 43 °C, if it is not of high quality the real temperature could be as high as 44 °C or as low as 42 °C.

If a measurement is accurate, that means that it's close to the actual value of the thing being measured. http://back2cloud.com/percent-error/percentage-error-calculation-in-chemistry.php However, their effect can be reduced by carrying out a measurement many times (if the opportunity exists) and working out an average value.

Paul G. Percent Error Worksheet What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take Copper's accepted density is 8.96 g/cm3.
