Which statement is true regarding the accuracy and precision of two classroom laboratory balances?

In a classroom laboratory setting, the choice that states the digital balance is both more accurate and more precise reflects the typical advantages associated with digital balances compared to mechanical ones.

Accuracy refers to how close a measurement is to the true value, while precision pertains to the consistency of measurements under the same conditions. Digital balances are designed with advanced technology that often allows for better calibration and reduces the impact of human error, leading to more accurate readings. Additionally, digital balances measure weight with greater specificity (usually to the hundredth or thousandth of a gram), making them more precise than mechanical balances, which often rely on analog readings that can be subject to interpretation and may vary slightly from one reading to another.

Mechanical balances can be quite effective but tend to rely on a system of beams and weights that may introduce variability in readings, plus they might not provide the same level of sensitivity and resolution as their digital counterparts. Therefore, the advantages of reduced error and improved measurement capability in digital balances support the assertion that they are both more accurate and more precise.
