The density of copper is listed as 8.94 g/cm3. Two students each make three density determinations of samples of the substance. Student A’s results are 7.3 g/mL, 9.4 g/mL, and 8.3 g/mL. Student B’s results are 8.4 g/cm3, 8.8 g/cm3, and 8.0 g/cm3.
Compare the two sets of results in terms of precision and accuracy.
