Explain the difference between accuracy and precision in measurements.

• Accuracy refers to how close a measurement is to the true value, while precision refers to how close repeated measurements are to each other.

• Accuracy and precision both refer to how close a measurement is to the true value.

• Accuracy refers to the consistency of measurements, while precision refers to the correctness of measurements.

• Accuracy and precision are interchangeable terms in measurements.

What are significant figures and why are they important in measurements?

• They are digits that carry meaning contributing to a measurement's precision.

• They are random numbers used in calculations.

• They are figures used in statistical analysis.

• They are numbers that do not affect the accuracy of measurements.
