Paragraph Styles 3. Three students make measurements (in m ) of the length of arod 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. (3 points) Student LI L2 L3 LA L SD u Student 1 1.4750 1.4759 1.4756 1.4749 Student 2 1.4719 1.4725 1.4705 1.4719 Student 3 1.4727 1.4718 1.4722 1.4715 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. (1 point) O- MX Accessibility: Investigate 9 Search hp 144 no 90 & 5 7 8 9
