What is percentage uncertainty?
Understand the Problem
The question is asking about the concept of percentage uncertainty, which typically refers to the measure of the uncertainty of a measurement in relation to the size of that measurement, expressed as a percentage. It is commonly used in science and engineering to convey the reliability of experimental results.
Answer
Percentage uncertainty is fractional uncertainty multiplied by 100.
Percentage uncertainty is fractional uncertainty expressed as a percent, calculated by multiplying the fractional uncertainty by 100.
Answer for screen readers
Percentage uncertainty is fractional uncertainty expressed as a percent, calculated by multiplying the fractional uncertainty by 100.
More Information
Percentage uncertainty can give an indication of how well-defined a measurement is: lower percentage uncertainties suggest more precise measurements.
Tips
A common mistake is confusing absolute uncertainty with percentage uncertainty; remember, percentage uncertainty requires multiplication by 100.
