Step By Step Guide. The absolute error is then divided by the true value resulting in the relative error which is multiplied by 100 to obtain the percentage error. The computation of percentage error involves the use of the absolute error which is simply the difference between the observed and the true value.
She has taught science courses at the high school college and graduate levels.
Percent Error Error Estimated Value x 100 Note. Calculation of percentage error. Because we do not know the actual percentage of students who smoke we can only approximate the sampling error by calculating the standard error. The computation of percentage error involves the use of the absolute error which is simply the difference between the observed and the true value.
