C. leas t del Niu 3. Three students make measurements (in m) of the length of a rod using a meter stick. Each student's measurements are tabulated in the table below. Using your calculator in statistic mode calculate the mean L, standard deviation S and uncertainty u of the measurements. Student L1 L3 L2 1.4711 L4 1.4715 SD u Student 1 1.4717 1.4722 1,4716 t.4754 1.4710 1.4753 1.4759 1.4756 1.4749 Student 2 Student 3 1.4719 1.4723 1.4705 1.4719 Note that the actual length of the rod is determined by a laser measurement technique to be 1.4715 m (this should be considered the standard value). a) State how one determines the accuracy of a measurement. Apply your idea to the measurements of the three students above and state which student has the most accurate measurement.
