Final answer:
Accuracy refers to how close a measurement is to the correct value, while precision refers to how close the individual measurements are to each other.
Step-by-step explanation:
Accuracy of a measured value refers to how close a measurement is to the correct value.
For example, if you measure the length of standard computer paper and obtain measurements of 11.1 in., 11.2 in., and 10.9 in., these measurements are quite accurate because they are very close to the correct value of 11.0 inches.
In contrast, if you obtained a measurement of 12 inches, it would not be very accurate.
Precision of measured values refers to how close the individual measurements are to each other. It indicates the consistency or reproducibility of the measurements.
For example, if you measure the length of standard computer paper and obtain measurements of 11.1 in., 11.2 in., and 10.9 in., these measurements are precise because they are very close to each other.
