What is the percent error between 960 and 680?
Use this calculator when comparing a experimental value to a theoretical value. We think you reached us looking for answers to questions like:
1) What is the percent error supposing 680 as the measured value and 960 as the calculated value? 2) What is the absolute error between 960 and 680 supposing 960 as the theoretical value? Or may be: What is the percent error between 960 and 680?See the solutions to these problems just after the Percent Error Calculator below.
How to calculate Percent Error  Step by Step Solution
The Percent Error Calculator uses this formula:% Error =  ( 
Experimental  Theoretical

)  Ã— 100  
Experimental 
The terms "Experimental" and "Theoretical" used in the equation above are commonly replaced with similar terms. Some terms also used for experimental are "measured," "calculated," or "actual" and for theoretical the terms "accepted" and "calculated" are frequently used.
The Percent Error can be a positive or a negative number. If the experimental value is greater than the theoretical value, the result will be positive. On the other hand, if the experimental value is smaller than the theoretical value, the result will be negative. See more about percent error here.
Here are the solutions to the questions stated above:
1) What is the percent error supposing 680 as the measured value and 960 as the calculated value?
Use the above formula to find the percent error. So, replacing the given values, we havePercent error = [(680  960) / 960] x 100
= (280 / 960) x 100
= 29.166666666667 % (negative error)
In this case we have a % of negative error because the experimental is smaller than the theoretical.
2) What is the absolute error between 960 and 680 considering 960 as the theoretical value?
This problem is not about percent or relative error, but about absolute error. The solution is very simple:Absolute error, or error = Experimental  Theoretical = 680  960 = 280 (negative error)
