But Sam measures 0.62 seconds, which is an approximate value. |0.62 − 0.64| |0.64| × 100% = 0.02 0.64 × 100% = 3% (to nearest 1%) So Sam was only We can do this multiplying both the numerator and the denominator by 20 We get (1 × 20)/(5 × 20) = 20/100 = 20% I hope what I explained above was Since the experimental value is smaller than the accepted value it should be a negative error.

Percent error or percentage error expresses as a percentage the difference between an approximate or measured value and an exact or known value. In this case, the real value is 10 and the estimated value is 9. 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.

It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value. Solve for percent error Solve for the actual value. Once you find the absolute value of the difference between the approximate value and exact value, all you need to do is to divide it by the exact value and multiply Steps 1 Know the formula for calculating percentage error.

The accepted value is 65, so your percent error is 15/65 = 0.2307 = 0.2307/1 = (0.2307 × 100)/(1 × 100) = 23.07/100 = 23.07% Percent error word problem #2 A In other words, amount of error = bigger − smaller Percent error word problem #1 A student made a mistake when measuring the volume of a big container.
