Observation (a) in cm
45.8
45.7
45.5
45.6
45.7
The formula for Average of all measurements =
a1+a2+a3+….+aii
(Here ‘i’ is the number of measurements observed.
amax , amin are maximum and minimum
measurements from the observation respectively)
Range of values R = amax– amin
Absolute uncertainty in measurement
Δa=Ri
