Accuracy vs. Precision Practice

Front

What is the definition of accuracy?

Back

Accuracy refers to how close a measurement is to the true or accepted value.

Front

What is the definition of precision?

Back

Precision refers to the consistency and repeatability of measurements, regardless of their closeness to the true value.

Front

What does it mean if measurements are both precise and accurate?

Back

It means the measurements are consistently close to the true value.

Front

What does it mean if measurements are precise but not accurate?

Back

It means the measurements are consistent but not close to the true value.

Front

What does it mean if measurements are accurate but not precise?

Back

It means the measurements are close to the true value but not consistent.

Front

What does it mean if measurements are neither precise nor accurate?

Back

It means the measurements are neither consistent nor close to the true value.

Front

How can you visually represent high accuracy and high precision?

Back

A cluster of points tightly grouped around the true value.

Front

How can you visually represent low accuracy and high precision?

Back

A cluster of points tightly grouped but far from the true value.

Front

How can you visually represent high accuracy and low precision?

Back

A spread of points that are close to the true value but not clustered.

Front

How can you visually represent low accuracy and low precision?

Back

A spread of points that are neither close to the true value nor clustered.
