Sometimes you will take the absolute value of the percent error because your estimated number could be less than the theoretical, meaning the calculation is negative. But an absolute value is always positive. A percent error can be left as a negative though, and this would be perfectly acceptable (or even preferred) depending on what you're doing.
Answer:In the sciences, a negative percent error indicates a low result. If you have a 0% error, then your observed (lab) result was exactly the same as the theoretical result. A 5% error could mean that your observed result was a little high. A negative percent error is possible; if your observed results were lower than the expected, then you would have a negative percent error. A -5% error could mean that your results were a little low.Having a negative percent error isn't worse than positive percent error -- it could mean the same thing. If you were to have a choice in having a 20% error and a -5% error, the negative percent error is more accurate.

Can the relative error be negative?
It can be.
What is percent error if you use a value of 3.14 for 3.14?
If you mean percent error of 3.14 versus pi, which is 3.14159..., the error is only 0.05%
What is the fractional error formula?
What is the formula for percent fractional error? (Physics)
Formula for percent error?
Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100
What is the reason for percent error?
Percent error is used when you are comparing your result to a known or accepted value. It is the absolute value of the difference of the values divided by the accepted value, and written as a percentage. Percent error is equal to the difference divided by the known times 100 percent.
What if the percent error is negative?
9f you are using the equation %error =[(oberved value - true value)/true value]x100 a negative percent indicates the observed value is less than the true value by the calculated percent.
Percent error formula?
Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.
Why are percent error values never negative?
all error value are suppose to be prefixed by a +/- symbol to show that they can be either + or -. As everybody understands this they just forget about it.
What does it mean if you get a negative number when you calculate for percent error?
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
What is relative errors?
Percent error.
What is the difference between low percent error and high percent error?
The difference between low percent error and high percent error is one is low and the other is high

Are percent deviation and percent error the same?
no
Is percent deviation the same as percent error?
No.
What is a high percent error mean?
high percent error is the absolute value of something that is multiplied
