The mass of a sample or iron ore is known to be 35.714 grams. You measure the mass of this sample using three different scales and obtain the following masses: 36.2 g, 35 g, 34.9 g and 35.9 g. The accepted tolerance for both error and for accuracy is 2%. With respect to accuracy and precision, how would you best describe these measurements? Hint: Determine the average mass, absolute deviation for each trail, the M.A.D, and Relative Deviation (percent).
