How do I calculate error?
Percent error is determined by the difference between the exact value and the approximate value of a quantity, divided by the exact value and then multiplied by 100 to represent it as a percentage of the exact value. Percent error = |Approximate value – Exact Value|/Exact value * 100.
What does it mean if percent error is negative?
If the experimental value is less than the accepted value, the error is negative. … If the experimental value is larger than the accepted value, the error is positive. Often, error is reported as the absolute value of the difference in order to avoid the confusion of a negative error.
