Measurement Error
 Measurement = cm 5.4 cm ? 5 cm Measurement = 5.4 cm Accuracy = cm 0.1 cm ? 1 cm Measurement = 5.4 cm Error = Accuracy = 0.1 cm cm ± 0.05 cm ? ± 0.5 cm → (0.1 ÷ 2)  Measurement = 20˚C ? 25˚C Measurement = 20˚C Accuracy = 5˚C ? 1˚C Measurement = 20˚C Error = Accuracy = 5˚C ± 2.5˚C ? ± 0.5˚C → (5 ÷ 2)  Measurement = 3:10 ? 2:15 Measurement = 3:10 Accuracy = 1 min ? 1 hour Measurement = 3:10 Error = Accuracy = 1 min ± 0.5 min ? ± 1 min  Measurement = 750 g ? 800 g Measurement = 750 g Accuracy = 50 g ? 100 g Measurement = 750 g Error = Accuracy = 50 g ± 25 g ? ± 0.5 g  Measurement = 65 km/h ? 70 km/h km/h Measurement = 65 km/h Accuracy = 5 km/h ? 10 km/h km/h Measurement = 65 km/h Error = Accuracy = 5 km/h ± 2.5 km/h ? ± 0.5 km/h km/h  Measurement = 2.8 m ? 2.4 m Measurement = 2.8 m Accuracy = 0.2 m ? 0.1 m Measurement = 2.8 m Error = Accuracy = 0.2 m ± 0.1 m ? ± 0.5 m |
