Answer Keys for Exercise #1 2. Relative Uncertainty = Uncertainty / AVR= 4/35 x 100 = 11% 3. Total = 222.6 AVR = 226.5/5 = 44.52 (two significant figures) Uncertainty (AVR of deviations) = (0.12+0.92+1.28+0.72+0.48)/5 = 0.7 (a s.f.) Result = 44.5 ± 0.7 , Best Estimate = 44.5 Relative Uncertainty = 0.7/44.5 x 100 = 1.57 % = 2% (a s.f.)
