Holly determines the identity of a several metallic samples. For each material, she measures the mass of five separate samples twice using a two beam balance. Then she she measures the dimensions of the samples twice using a ruler or calipers and calculating the
volume. Finally she graphs the average mass versus average volume and determines the density of the samples from the best fit line.
Examine the procedure and elaborate on what modifications to the experimental procedure will increase the accuracy and precision of
this experiment
