## Absolute And Relative Error Calculator

As an alternative, each actual value (At) of the series in the original formula can be replaced by the average of all actual values (Āt) of that series. Say we measure any given quantity for n number of times and a1, a2 , a3 …..an are the individual values then Arithmetic mean am = [a1+a2+a3+ …..an]/n am= [Σi=1i=n ai]/n The terms "Experimental" and "Theoretical" used in the equation above are commonly replaced with similar terms. This negative result provides additional information about the experimental result.

Although the concept of MAPE sounds very simple and convincing, it has major drawbacks in practical application [1] It cannot be used if there are zero values (which sometimes happens for Wikipedia® is a registered trademark of the Wikimedia Foundation, Inc., a non-profit organization. First, there is no need to keep track of which of the two quantities, V1 or V2, the change is expressed relative to, since, under the conditions of the approximation, the Absolute And Relative Error Examples The best way to learn how to calculate error is to go ahead and calculate it.
