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. Percent error or percentage error expresses as a percentage the difference between an approximate or measured value and an exact or known value. Working... You measure the dimensions of the block and its displacement in a container of a known volume of water.
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. It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value. Since the experimental value is smaller than the accepted value it should be a negative error. Without "Absolute Value" We can also use the formula without "Absolute Value".
