The density of a sample of metal is calculated using these three different sets of dаta: 1.2 g/mL, 1.4 g/mL, and 1.1 g/mL. If the true density of the metal is 1.2 g/mL, what can be said about these calculated density values?

The set is both accurate and precise.

The set is accurate but not precise.

The set is precise but not accurate.

The set is neither accurate nor precise.

Accurate data means the data experimentally obtained are close to the true value. Precise data means the data obtained are close to one another. In this case, the data are close to the true value which is 1.2 and the data are relatively close to one another. Hence the set is both accurate and precise.
