You measure the dimensions of the block and its displacement in a container of a known volume of water. Updated September 14, 2016.

The difference between the actual and experimental value is always the absolute value of the difference. |Experimental-Actual|/Actualx100 so it doesn't matter how you subtract. Comparing Approximate to Exact "Error": Subtract Approximate value from Exact value. Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of Negative Percent Error Thanks for letting us know.

Copper's accepted density is 8.96 g/cm3. The formula for calculating percentage error is simple:[1]'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The approximate value is the estimated value, and the exact value is the real value. This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.Percent Error Example http://back2cloud.com/percent-error/percentage-of-error-calculation-formula.php How to solve percentage error without the exact value given?
