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 However if percent error is equal to 100 percent or -100 percent, then there is only one calculated solution and one solution of infinity.

Thanks, You're in! This can give a positive or negative result, which may be useful to know. It is often used in science to report the difference between experimental values and expected values.The formula for calculating percent error is:Note: occasionally, it is useful to know if the error Clyde Lettsome 3.088 προβολές 10:28 Precision, Accuracy, Measurement, and Significant Figures - Διάρκεια: 20:10.

In this case, since there is not one accepted value for the speed of a rolling body, we will use the percent difference to determine the similarity of the measurements. Since the experimental value is smaller than the accepted value it should be a negative error. Two-Point-Four 32.988 προβολές 2:12 Φόρτωση περισσότερων προτάσεων… Εμφάνιση περισσότερων Φόρτωση...
