Physics and Physical Measurement Every measured value has uncertainty. Mean: 14.37 s Residuals: 14.37 – 13.84 = 0.53 15.31 – 14.37 = 0.94 Measurements of time are taken as: 14.23 s, 13.91 s, 14.76 s, 15.31 s. 13.84 s, 14.18 s. What value should be reported? Greatest Residual: 0.94 Reported Value: 14.37 s ± 0.94 s = mean ± greatest residual 1. Measurement: Record as many significant figures as the calibration of the measuring instrument allows plus one estimated digit. 2. Uncertainty: Record a reasonable uncertainty estimate that a) has one significant digit, and b) matches the measurement in place value (decimal place). Voltage ± uncertainty V ± ΔV 11.6 V ± 0.2 V Percentage Uncertainty ΔV/V ∙ 100% 0.2 V / 11.6 V ∙ 100% = 1.7 % |
