Once you understand the difference between Absolute and Relative Error, there is really no reason to do everything all by itself. http://compaland.com/relative-error/what-is-the-relative-error-formula.html

Your absolute error is 20 - 18 = 2 feet (60.96 centimeters).[3] 2 Alternatively, when measuring something, assume the absolute error to be the smallest unit of measurement at your disposal. But, if you tried to measure something that was 120 feet long and only missed by 6 inches, the relative error would be much smaller -- even though the value of Trending Now Tatyana Ali Ariana Grande Alicia Keys Jeanine Pirro Online MBA Credit Cards Kim Yo Jong Cable TV Jennifer Lopez Jay Cutler Answers Relevance Rating Newest Oldest Best Answer: Good Make the measurement with an instrument that has the highest level of precision. http://www.regentsprep.org/regents/math/algebra/am3/LError.htm

Q: Where did algebra come from? Any measurements within this range are "tolerated" or perceived as correct. For example, if you know a length is 3.535 m + 0.004 m, then 0.004 m is an absolute error. If the formula was "x squared +...
