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?)

But as a general rule: The degree of accuracy is half a unit each side of the unit of measure Examples: When your instrument measures in "1"s then any value between

hi, when u did "0.05*2)/11.30 * 100 = 0.88%" why did u multiply 0.05 by two? Evaluation - What if an Equipment Error is greater than 5%?—  Recommend a change to a more accurate named example of measuring equipment—  Suggest than larger (suggest an amount) amounts are The human reaction times can vary and but I estimate around ±0.1s.
