Percent Error Equations


Example: You measure the plant to be 80 cm high (to the nearest cm) This means you could be up to 0.5 cm wrong (the plant could be between 79.5 and Ex: 10 - 9 = 1 3 Divide the result by the real number. Updated September 14, 2016. Ex:-1/10 = -0.1 4 Find the absolute value of the result. this content

Just add the percentage symbol to the answer and you're done. so divide by the exact value and make it a percentage: 65/325 = 0.2 = 20% Percentage Error is all about comparing a guess or estimate to an exact value. 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 Note, this has two solution due to the absolute value in the percent error equation.
