C. Mittal · Indian percent error when actual value is zero Institute of Technology Roorkee This is not necessary that one should find relative and % error for very small values. They are important when your actual(exact) value is very large. Mar 7, 2014 Geen percent error when true value is 0 Paul V · Tata Consultancy Services Limited Sir, I am working on Finite Element Analysis for an aerospace company in USA. The Company Spoke wants to get ma computed values sometimes validated by hand calculation. And sometimes the actual stress value may be zero. but the numerical analysis value varies by less than 1. And I was wondering how to make it in percentage. ! Mar 7, 2014 Hanno
Percent Error When Expected Value Is Zero
Krieger · retired from Justus-Liebig-Universität Gießen I try to follow. If you get experimental results which allow a statistical analysis (gauss or poisson distributions) you use the established methods of error calculation. If you have only a small number of results it´s without any sense to calculate average values or medians etc. So if you spent a little bit more information (possibly with an example) I could find a tip. Mar 7, 2014 Hanno Krieger · retired from Justus-Liebig-Universität Gießen Like to add a remark. You can calculate errors not before you define a reference value. Thats what I´m missing most in your question. Mar 7, 2014 Joseph Dubrovkin · Western Galilee College You can calculate lim(deltaX/X) when X->0 using l'Hôpital's rule or graphically. The relative error is important when X->0. E.g., detection limit. Mar 8, 2014 Luca Dimiccoli · Vrije Universiteit Brussel Notice that deltaX does not satisfy all the hypotheses of the Hopital's rule. Moreover, the limit that is suggested does not exist. Mar 8, 2014 Manuel Antonio Borregales Reverón · University of Bergen I think the key is the value of references that you can use, for example I try to simulate a sum of forces acting on an object. I

The formula is given http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/ by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he determined that this phenomenon was due to the fact that the speed of light was finite, and subsequently estimated its velocity to be approximately 220,000 km/s. The current accepted value of the speed of light is almost 299,800 km/s. What was the percent error of Rømer's estimate?Solution:experimental value = 220,000 km/s = 2.2 x 108 m/stheoretical value = 299,800 km/s 2.998 x 108 m/s So Rømer was quite a bit off by our s

The formula for calculating percent error is (estimated value - true value) / true value * 100. My estimated value is 0.1 while the true value is 0, which would give me (0.1 - 0) / 0 * 100. Since dividing by 0 is impossible, how can i find the percent error? Thank you!! 1 following 4 answers 4 percent error when Report Abuse Are you sure you want to delete this answer?

Percent error is undefined when the denominator is zero. It's just a case where the concept of percent error isn't useful. Source(s): elifino · 7 years ago 0 Thumbs up 1 Thumbs down Comment Add a comment Submit · just now Asker's rating Report Abuse Certainly you end up dividing by zero, you cannot calculate percent error when the true value is zero. I think the idea is that you should have any error when measuring a quantity of zero. It's hard to make a measurement mistake if you have zero of the unit! To be honest, I had never considered this before, so thank you!
