    Error Percent Value

SUMMARY

The percent error formula, defined as (|accepted - measured| / |accepted|) * 100%, results in a 100% error when the measured value is 0, regardless of the accepted value. This outcome indicates a significant discrepancy in measurement, suggesting potential errors in the experimental process or a lack of precision in the method used. If a small value was expected, obtaining a measured value of 0 raises questions about the validity of the experiment and the accuracy of the measurement techniques employed.

How do you get the percent error when the accepted value is very small and the measured value is 0? No matter what the accepted value is if the measured value is 0 the percent error is always 100% based on the formula:

(|accepted-measured|/|accepted|)*100%

thats right. if you get 0, that's a 100% error. but I would question the validity of the experiment if you get 0 when it should have just been a small value. either you made a mistake at some point or the experiment wasn't apporpriate for getting that value, ie, it wasn't precise enough.
