I got an experimental value that is lower than my accepted value, and that's going to make my error negative. what do I do?
That's a good suggestion. But what if I can't repeat the experiment? How do I calculate the error with a negative value?
Good question. In this case, you would take the absolute value of the difference between your experimental value and the accepted value, and then divide that by the accepted value. This would give you a positive percentage error, which can still be used to assess the accuracy of your experimental results.
