Warnings If taking the regents exam, make sure you round correctly EditRelated wikiHows How to Compare and Order Fractions How to Find the Area of a Square Using the Length of Absolute Error This simple equation tells you how far off you were in comparison to the overall measurement.

Then find the absolute deviation using formulaAbsolute deviation $\Delta$ x = True value - measured value = x - xoThen substitute the absolute deviation value $\Delta$ x in relative error formula Relative Error Chemistry Laden... So we use the maximum possible error. http://mathworld.wolfram.com/RelativeError.html For example, if your experimental value is in inches but your real value is in feet, you must convert one of them to the other unit of measurement.

To continue the example of measuring between two trees: Your Absolute Error was 2 feet, and the Actual Value was 20 feet. 2ft20ft{\displaystyle {\frac {2ft}{20ft}}} Relative Error =.1feet{\displaystyle =.1feet}[7] 2 Multiply Absolute And Relative Error In Numerical Methods A low relative error is, of course, desirable. If the object you are measuring could change size depending upon climatic conditions (swell or shrink), be sure to measure it under the same conditions each time. You can compare your own results to get Absolute Error, which measures how far off you were from the expected results.

you didn't measure it wrong ... Machines used in manufacturing often set tolerance intervals, or ranges in which product measurements will be tolerated or accepted before they are considered flawed. The precision of a measuring instrument is determined by the smallest unit to which it can measure. 2. b.) The relative error in the length of the field is c.) The percentage error in the length of the field is 3.
