The value which is being referred to helps us determine how significant our mistakes are during any analysis. In this paper, you will learn the necessary formulas for calculations, as well as arm yourself with valuable tips on this topic.
Why Do We Calculate Percentage Error?
The purpose of the PE calculation is to estimate how close the measured value is to the true value. You can define percent deviation yourself using the appropriate formula or using a special calculator. Another option is to train and develop computational skills under the guidance of a tutor. There are many specialists in different fields of mathematics on UpskillsTutor.
How to Calculate Percentage Error?
In the sphere of project management, the percentage of completion is often used. For example, your monthly plan contains 56 tasks, of which you have already completed 31. Use percent complete formula C%=TC/TT*100=31/56*100=55%. It turns out that at the moment, the productivity of your work is 55%.

Difference Between Percentage Error, Absolute Error, and Relative Error
Let us start by defining terminology.
Pay special attention to formulas.
AE is an indicator of gauging uncertainty. The RE depends on two variables: the AE and the experimental value of the gauging.
Below is the relative error formula.
The latter one can be represented either as a percentage (PE) or as a fraction (partial uncertainty).
Complex experimental physical quantifying and solving problems of mathematical investigation and many other fields of science are associated with the computation of various types of errors. Therefore, it is crucially to have good training. Why not take some private lessons from a math tutor?
This is the shortest way to rapidly and efficiently acquire quality knowledge. And here is why:
- the ability to quickly get rid of difficulties and knowledge gaps;
- special emphasis on practical tasks;
- control over the implementation of exercises;
- valuable advice from a professional.
