Answer:
Precision means that independent measurements are close to each other.
Accuracy means that independent measurements are close to a known or accepted value.
Explanation:
Accuracy refers to how close the measurements of a measurement system are to the true value while precision refers to how close the measurements are to each other. In other words, accuracy is the closeness of the value of one or more independent measurements to a true value, and precision is the closeness of two or more values of several measurements to each other.
Both are independent of each other, that is to say that the results in the values of a measurement can be precise and not exact, and vice versa.
So:
Precision means that independent measurements are close to each other.
Accuracy means that independent measurements are close to a known or accepted value.
