The Density of a Solid Experiment 1A After reviewing data and observations, the density derived from the calculated volume is more precise than the density derived from the measured volume. Precision is the closeness to a series of repeated measurements. In other words, how precise a measurement is depends on how closely reproducible the same measurements are. The density derived from the calculated volume is reproducible and is sure to give precise measurements because there is very little room for error. The Vernier calipers allow us to measure length and diameter down to the very millimeter, leaving less room for error than a graduated cylinder would. The marks on a graduated cylinder are less frequent and when adding a certain amount of water, it is hard to put the exact same amount every single time, so you may get different measurements for the volume.
