Question

What is degree of accuracy ,explain in brief alongwith examples​

Answer 1

Answer:

Accuracy and precision are two important factors to consider when taking data measurements. Both accuracy and precision reflect how close a measurement is to an actual value, but accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value.

Key Takeaways: Accuracy Versus Precision

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).

Percent error is used to assess whether a measurement is sufficiently accurate and precise.

You can think of accuracy and precision in terms of hitting a bull's-eye. Accurately hitting the target means you are close to the center of the target, even if all the marks are on different sides of the center. Precisely hitting a target means all the hits are closely spaced, even if they are very far from the center of the target. Measurements that are both precise and accurate are repeatable and very near true values.

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.
