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 precision of a measuring instrument is determined by the smallest unit to which it can measure. 2. The percentage error gives you the difference between the approximate and exact values as a percentage of the exact value and can help you see how close your guess or estimate Percent of Error: Error in measurement may also be expressed as a percent of error. http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/

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 Should the accepted or true measurement NOT be known, the relative error is found using the measured value, which is considered to be a measure of precision. chemgirl 1,985 views 5:14 Loading more suggestions...
