The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. Can Percent Error Be Zero For instance, the absolute difference of 1 between 6 and 5 is more significant than the same absolute difference between 100,000,001 and 100,000,000. are the integers modulo 4 a field? The other problem is more general.

Images and meme posts Image-only posts should be on-topic and should promote discussion. Posteriori Analysis Normalization with a factor of 100, as done for percent, yields the derived unit centineper (cNp) which aligns with the definition for percentage change for very small changes: D c N C.

Also, do not put more than two traces on a graph unless you are trying to show a progression of data. Obviously, you can not divide by zero, so how do you find the percent error without using statistics (distribution)? 2 commentsshareall 2 commentssorted by: besttopnewcontroversialoldrandomq&alive (beta)[–]trickyben2 2 points3 points4 points 4 years ago(1 child)You Here we list many of the more common mistakes made in the writing of lab reports (and other technical literature as well). Relative Error Calculator The equation for % error is [absolute value(calculated value - theoretical value) / theoretical value] * 100, but 0 can't be in the denominator, because you can't divide by 0.
