Yes No Cookies make wikiHow better. This feature is not available right now. This means that you should subtract the real value from the estimated value. The result of the difference is positive and therefore the percent error is positive.

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 Todd also writes many of the example problems and general news articles found on the site. Please try again later.

The post has been corrected. Percent Error Calculator You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. 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 http://www.ajdesigner.com/phppercenterror/percent_error.php 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

Also, Wikipedia (not the best source, I know) and Wolfram indicate division by $B$,as does this page. –HDE 226868 Oct 22 '14 at 1:30 @BenCrowell I know from your What Is A Good Percent Error If you're testing an experiment against theory, there's no way to know whether a 0.03% difference is consistent with the theory or inconsistent with it, because it depends on how much Flag as... experimental-physics error-analysis share|cite|improve this question asked Oct 22 '14 at 0:52 gyeox29ns 485 3 Percent error is almost never of interest, so the real answer is that working scientists would

Percentage is always positive, so we invoke absolute value to get $$E=\frac{|A-B|}{B}\times 100$$ Actually, we can also use $$E=\frac{|B-A|}{B}\times 100$$ Percent error is always taken with respect to the known quantity http://physics.stackexchange.com/questions/142488/what-is-logical-way-to-calculate-percentage-error Bozeman Science 175,902 views 7:05 percent error.mp4 - Duration: 5:14.
