Three students make measurements (inm) 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 L SD Student I 1.717 1.4711 1.472 1.4715 Student 2 1.-1753 1750 1.4756 11.4749 Student 3 1.4719 1.4723 11.19 u Note that the actual length of the rod is determined by a laser measurement technique to be 1.4716 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. b) Do any of the three students have data that suggest the possibility of an error? If so, state which student it is, and state how the data indicate your conclusion.
