Front

What does high accuracy and high precision mean in measurements?

Back

Measurements are both close to the true value and close to each other.

Front

Define precision in the context of measurements.

Back

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

Front

What does accuracy refer to in measurements?

Back

Accuracy means the measurement is close to the true value.

Front

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

Back

The measurements are close to each other but not close to the true value.

Front

How is accuracy defined in relation to accepted values?

Back

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

Front

What is the difference between accuracy and precision?

Back

Accuracy refers to closeness to the true value, while precision refers to the closeness of measurements to each other.

Back

High precision but low accuracy.

Front

What would a bullseye with darts spread out but centered around the target indicate?

Back

High accuracy but low precision.

Front

If a set of measurements is both accurate and precise, what can be said about them?

Back

They are close to the true value and close to each other.

Front

What is an example of low accuracy and low precision?

Back

Darts thrown randomly with no clustering and far from the bullseye.
