The difference between the measured or inferred value of a quantity and its actual value , given by. (sometimes with the absolute value taken) is called the absolute error. The absolute error of the sum or difference of a number of quantities is less than or equal to the sum of their absolute errors.
Formula to Find Absolute Error :
The relative error is the absolute error divided by the magnitude of the exact value. The percent error is the relative error expressed in terms of per 100.
Formula to Find Relative Error :
The percentage error, also known as percent error, is a measure of how inaccurate a measurement is, standardized to how large the measurement is. It is the relative error expressed in terms of per 100.
Formula to Find Percentage Error :
Observed Value=9.0098, True Value=10 Ans. Absolute Error =( Vtrue - Vobserved ) = ( 10 - 9.0098 ) = 0.9902
