Percent Error Calculation

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.

If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. Negative Percent Error This is also called the accepted, experimental or true value.Note due to the absolute value in the actual equation (above) there are two value.

The result of the difference is positive and therefore the percent error is positive. Percent Error Chemistry A large error means there may be something wrong with the experiment or equipment.
