What is percent uncertainty?
Understand the Problem
The question is asking for an explanation of what percent uncertainty is, which relates to measuring the accuracy or precision of a value in scientific or mathematical contexts. It typically involves expressing the uncertainty of a measurement as a percentage of the value of that measurement.
Answer
Fractional uncertainty expressed as a percentage.
Percent uncertainty is the fractional uncertainty expressed as a percentage.
Answer for screen readers
Percent uncertainty is the fractional uncertainty expressed as a percentage.
More Information
It is calculated by dividing the absolute uncertainty by the measured value and multiplying the result by 100.
Tips
A common mistake is to confuse absolute uncertainty with percent uncertainty. Always convert the absolute uncertainty relative to the measured value before multiplying by 100.
