Question

In an experiment refractive index of glass was observed to be 1.45 1.56 1.54 1.44 1.54 and 1.53 the mean absolute error in the experiment is​

Answer 1

Mean value of measurements = n = Sum of all measurements / 6 = 1.51 then 0.06 , 0.05, 0.03, 0.07 , 0.03, 0.02 (only absolute value)
Mean value of Absolute error = Δn = 0.043
