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 the $Y(i)$ cover a very large range, minimizing the sum of squares of residuals give an incredible weight to the highest values and the small values of $Y$ play How To Calculate Relative Error In Physics
