Accuracy and precision

Front

What is the definition of accuracy?

Back

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

Front

What is the definition of precision?

Back

Precision is a measure of how close measurements come to each other when they are made in the same way.

Front

What does it mean if a set of data is both precise and accurate?

Back

It means the data points are close to each other and also close to the actual value.

Front

What is an example of high accuracy and high precision?

Back

A set of measurements that are all very close to each other and also very close to the true value.

Front

What is an example of low accuracy and high precision?

Back

A set of measurements that are very close to each other but far from the true value.

Front

What is an example of high accuracy and low precision?

Back

A set of measurements that are close to the true value but vary widely from each other.

Front

What is an example of low accuracy and low precision?

Back

A set of measurements that are neither close to each other nor close to the true value.

Front

How can you improve accuracy in measurements?

Back

By using calibrated instruments and following proper measurement techniques.

Front

How can you improve precision in measurements?

Back

By using the same method consistently and minimizing variability in the measurement process.

Front

What is the relationship between accuracy and precision?

Back

Accuracy refers to closeness to the true value, while precision refers to consistency among measurements.
