First of calculating the error by subtracting one value from others and ignore any minus sign We get decimal number by dividing the error by the exact value Convert the results into a percentage by multiplying by 100 and adding a 100 sign. Now you get your percent error. To calculate the percentage error just follow the formula in this lesson.
Percent Error Calculation Steps Subtract one value from another.
The value obtained after this is the percentage error. The absolute error is then divided by the true value resulting in the relative error which is multiplied by 100 to obtain the percentage error. In calculating percent error We need to get the experimental value and the value which you are aiming at which is the actual value first. Divide the error by the exact value we get a decimal number Step 3.
