Accuracy refers to the degree to which a measurement, calculation, or estimate is close to the true value or target value. It is a measure of how correct a result is.

Precision, on the other hand, refers to the degree of consistency or reproducibility of a measurement or result, regardless of whether it is accurate or not. It is a measure of how repeatable a result is.

In summary, accuracy is about how correct a result is, while precision is about how consistent a result is.
