1.2 Accuracy and Precision

Front

What is Precision?

Back

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

Front

What is Accuracy?

Back

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

Front

Which student is the most ACCURATE?

Back

The student whose measurements are closest to the accepted value.

Front

Describe the accuracy and precision of a measurement that is not accurate and not very precise.

Back

The measurements are far from the accepted value and vary widely from each other.

Front

What does a bullseye with low accuracy and high precision indicate?

Back

The measurements are clustered together but far from the target value.

Front

What is the difference between accuracy and precision?

Back

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

Front

If a measurement is very accurate but not precise, what does that mean?

Back

The measurements are close to the accepted value but vary significantly from each other.

Front

What is an example of high precision but low accuracy?

Back

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

Front

How can you improve precision in measurements?

Back

By using the same method and equipment consistently.

Front

What is a common tool used to measure length accurately?

Back

A ruler or a caliper.
