If you measure the same object two different times, the two measurements may not be exactly the same. Maximum Percentage Error Equipment Error Although it is optional to assess equipment errors it is highly recommended For each different use of equipment calculate the % error Calculate the error on the smallest quantity So: Absolute Error = 7.25 m2 Relative Error = 7.25 m2 = 0.151... 48 m2 Percentage Error = 15.1% (Which is not very accurate, is it?)
