What is Precision?

Back

Precision refers to the consistency of measurements or results. It indicates how close the measurements are to each other, regardless of whether they are close to the true value.

Front

How can you improve accuracy in measurements?

Back

By using more reliable measuring tools and techniques, and by calibrating them against known standards.

Front

What is the difference between accuracy and precision?

Back

Accuracy is about correctness (closeness to the true value), while precision is about consistency (closeness of measurements to each other).
