This value is your 'error'.  continue reading below our video 4 Tips for Improving Test Performance Divide the error by the exact or ideal value (i.e., not your experimental or measured The lower the standard deviation, the better (in this case) the measurements are. The absolute value of a positive number is the number itself and the absolute value of a negative number is simply the value of the number without the negative sign, so

Percent error -- take the absolute value of the error divided by the theoretical value, then multiply by 100.

The formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value. 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 The absolute value of the error is divided by an accepted value and given as a percent.|accepted value - experimental value| \ accepted value x 100%Note for chemistry and other sciences, Ex:-1/10 = -0.1 4 Find the absolute value of the result.

If you want to know how to calculate percentage error, all you need to know is the approximate and exact value and you'll be on your way. Simply multiply the result, 0.1, by 100.

Did this article help you? How to solve percentage error without the exact value given? This means that you should subtract the real value from the estimated value. And we can use Percentage Error to estimate the possible error when measuring.

Please select a newsletter. In this example, the student has measured the percentage of chlorine (Cl) in an experiment a total of five times. But Sam measures 0.62 seconds, which is an approximate value. |0.62 − 0.64| |0.64| × 100% = 0.02 0.64 × 100% = 3% (to nearest 1%) So Sam was only Flag as...
