Absolute and Relative Error

Instructions

This drill allows you to practice calculating the absolute and relative errors between an experimentally determined result and the expected value. Enter your calculated values in the spaces provided. The value for the error must be precise to the nearest thousandth, and the value for the relative error must be correct to at least 3 significant figures. Select "Check Answer" to see if your answer is correct; select "Give Up" if you want to see the answer.

The data:

Experimentally determined result:  -422.412
                  Expected value:   391.502

         Error:  
Relative Error:  %
