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 How to Calculate HereÂ is theÂ way to calculate a percentage error: Step 1: Calculate the error (subtract one value form the other) ignore any minus sign.

You calculate the density of the block of aluminum to be 2.68 g/cm3. A percent error of zero indicates that an experimental value is exactly the same as the actual, accepted value. Difference Between Negative And Positive Feedback A percent error of zero indicates that an experimental value is exactly the same as the actual, accepted value. Difference Between Negative And Positive Feedback In Homeostasis As a result, there are many options for how to define relative difference and which one is used depends on what the comparison is being used for.
