Answer:
Accuracy
There are two common definitions of accuracy. In math, science, and engineering, accuracy refers to how close a measurement is to the true value.
If your scale gives you values of 49.8, 50.5, 51.0, and 49.6, it is more accurate than the first balance but not as precise.
Precision
Precision is how consistent results are when measurements are repeated. Precise values differ from each other.
If you take measurements of the mass of a 50.0-gram standard sample and get values of 47.5, 47.6, 47.5, and 47.7 grams, your scale is precise, but not very accurate

Accuracy is how close a value is to its true value.
An example is how close an arrow gets to the bull's-eye center.
Precision is how repeatable a measurement is.
An example is how close a second arrow is to the first one (regardless of whether either is near the mark).
