The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs. Negative Percent Error Yes No Cookies make wikiHow better.

The theoreticalvalue (using physics formulas)is 0.64 seconds. Since the experimental value is smaller than the accepted value it should be a negative error. See percentage change, difference and error for other options. The absolute value of a positive number is the number itself and the absolute value of a negative number is simply the value of the number without the negative sign, so
