You do not add the percentage error but the actual error.

What is the percent of error of 2.5?
2.5% error. Hence, theoritical - 2.5% = actual.
What does the term percent error refer to?
An error is the difference between a predicted value and the actual, observed, value. The percent error tells the user how close or how far off one was from the actual value in the form of a percentage.
What is the type of percent that compares the inaccuracy of an estimate to the actual amount?
Error
What is The percent difference between an observed value and its actual value?
It is the observed error.
How can you calculate standard error in volume?
The standard error is calculated by dividing the actual volume by the experimental volume. This is a common technique used in the laboratory.
How do you show percent error?
Percent error = (actual value - theoretical value) / theoretical value * 100%
When will use percent difference and percent error?
When Percent Equal 100%

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.
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 |.
What is the type of percent that compares the inaccuracy of an estimate to the actual amount?
Error
What is the measured the density of Copper to be 68.7 gcm3 The accepted density of Copper is 63.5 gcm3 What was your percent error?
percent error = [(experimental value - actual value)/(actual value)] x 100 so in this case: % error = [(68.7-63.50)/(63.5]x100
What is type of percent that compares the inaccuracy of an estimate to the actual amount?
Percentage error.
What is The percent difference between an observed value and its actual value?
It is the observed error.
What is the difference between the low percent error and the high percent error?
If it's high that means it's very off and away from the actual value. If you find a low percent error it is very close or close to the true value.
How can you calculate standard error in volume?
The standard error is calculated by dividing the actual volume by the experimental volume. This is a common technique used in the laboratory.
