Solving for the uncertainty in k A gives its value as 147 10 3 or 00015 ppm 1. When calculating percent uncertainty absolute uncertainty is used. The percentage uncertainty is the fractional uncertainty multiplied by 100 to give a percentage.
Find the mean of the values Find the range and half it this is the absolute uncertainty.
Percentage uncertainty in volume percentage uncertainty in L percentage uncertainty in W percentage uncertainty in D 25 37 88 Therefore the uncertainty in the volume expressed in cubic meters rather than a percentage is. 64 10 5 0028 2341 2 u 0186 2. Squaring both sides of the equation gives. 4 c m 1 0 0 5.
