The following sets of measurement for the density of a small cylinder of aluminum were given. The 'accepted' density of aluminium is 2.702 g/cm3. SET A SET B 2. 240 g/cm³ 2.700 g/cm³ 2. 690 g/cm3 2.705 g/cm3 2. 450 g/cm³ 2.703 g/cm³ 2. 150 g/cm3 2.701 g/cm3 1. Calculate the average value for each set of density. 2. Calculate the % error for each set of values. 3. Compare the average value for each set with the accepted value: Which student's data is more accurate? Which student's data is more precise? 4. Compare the percentage error for each set: Which student's data is more accurate? Which student's data is more precise?
