What is the difference between a crosscut sled and a table saw boat? Solve for the measured or observed value.Note due to the absolute value in the actual equation (above) there are two solutions. However, when I deal with nominal measurement, not the upper or lower limits, I would certainly say my nominal dimension has so much %error. Copper's accepted density is 8.96 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 Ex: 10 - 9 = 1 3 Divide the result by the real number.

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 What Is A Good Percent Error Percentage Difference Percentage Index Search :: Index :: About :: Contact :: Contribute :: Cite This Page :: Privacy Copyright © 2014 MathsIsFun.com Physics Tutorial: % Error & % Difference Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of 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
