WebApr 8, 2024 Β· So far, we have dealt only in absolute uncertainties - uncertainties that can be measured in the units our measured value is in. For example, someone's height could be 180 cm with an absolute uncertainty of Β± 10cm. When we have to combine uncertainties by multiplying or dividing data, we must use percentage uncertainties as well.
