Accuracy, Precision, and Percent (%) Error

Front

What is the definition of precision in measurements?

Back

Precision refers to the repeatability and consistency of measurements, indicating how close the measurements are to each other.

Front

What is the definition of accuracy in measurements?

Back

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

Front

What is percent error?

Back

Percent error is a measure of how inaccurate a measurement is, expressed as a percentage of the true value.

Front

How do you calculate percent error?

Back

Percent Error = |(Measured Value - True Value)| / True Value x 100%.

Front

What does high precision but low accuracy indicate?

Back

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

Front

What does high accuracy and high precision indicate?

Back

It indicates that measurements are both close to the true value and consistent with each other.

Front

What does low accuracy and low precision indicate?

Back

It indicates that measurements are neither close to the true value nor consistent with each other.

Front

What does a bullseye with all darts clustered together but far from the center represent?

Back

It represents high precision but low accuracy.

Front

What does a bullseye with darts spread out but centered around the target represent?

Back

It represents high accuracy but low precision.
