Ifyou need to knowpositive or negative error, thisis done by dropping the absolute value brackets in the formula.In most cases, absolute error is fine. This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.Percent Error Example Calculate Percent ErrorLast modified: November 28th, 2016 by Todd HelmenstineShare this:GoogleFacebookPinterestTwitterEmailPrintRelated This entry was posted in Measurement and tagged example problems, experiments, homework help, measurement, percent error on May 16, 2014 This means that you should subtract the real value from the estimated value.

## How To Calculate Percentage Error In Physics

The result of the difference is positive and therefore the percent error is positive. I may also apply a curve to the fourth exam depending on performance. A: The general chemical formula for paraffin wax is CnH2n+2, where "n" has an average value between 20 and 30. For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation
