Reply ↓ Mary Andrews February 27, 2016 at 5:39 pm Percent error is always represented as a positive value. This is a big difference from getting a positive percent error, which means the experimental value is a velocity that is greater than the speed of light (violating the theory of In general we can say that the absolute difference |Δ| is being scaled by some function of the values x and y, say f(x,y). Corresponding values of percent difference would be obtained by multiplying these values by 100.

In some cases a positive percent error is typical, but applications such as chemistry frequently involve negative percent errors. It is important for any scientists performing this reaction to report on its accuracy.
