Understanding Accuracy and Precision

What is the main difference between accuracy and precision?

• Both accuracy and precision are about correctness.

• Accuracy is about correctness, while precision is about consistency.

• Both accuracy and precision are about consistency.

• Accuracy is about consistency, while precision is about correctness.

In the dartboard analogy, what does low accuracy and low precision look like?

• Darts are both close to each other and the bull's eye.

• Darts are close to each other but far from the bull's eye.

• Darts are scattered and far from the bull's eye.

• Darts are close to the bull's eye but not to each other.

What does low accuracy but high precision mean in the dartboard analogy?

• Darts are scattered and far from the bull's eye.

• Darts are both close to each other and the bull's eye.

• Darts are close to each other but far from the bull's eye.

• Darts are close to the bull's eye but not to each other.

In the dartboard analogy, what does high accuracy but low precision look like?

• Darts are both close to each other and the bull's eye.

• Darts are close to the bull's eye but not to each other.

• Darts are close to each other but far from the bull's eye.

• Darts are scattered and far from the bull's eye.

What does high accuracy and high precision mean in the dartboard analogy?

• Darts are scattered and far from the bull's eye.

• Darts are close to each other but far from the bull's eye.

• Darts are close to the bull's eye but not to each other.

• Darts are both close to each other and the bull's eye.

In the weighing example, what does low accuracy and low precision indicate?

• Measurements are both correct and consistent.

• Measurements are correct but inconsistent.

• Measurements are scattered and incorrect.

• Measurements are consistent but incorrect.

What does low accuracy but high precision mean in the weighing example?

• Measurements are correct but inconsistent.

• Measurements are scattered and incorrect.

• Measurements are consistent but incorrect.

• Measurements are both correct and consistent.

In the weighing example, what does high accuracy but low precision indicate?

• Measurements are consistent but incorrect.

• Measurements are correct but inconsistent.

• Measurements are scattered and incorrect.

• Measurements are both correct and consistent.

What does high accuracy and high precision mean in the weighing example?

• Measurements are consistent but incorrect.

• Measurements are scattered and incorrect.

• Measurements are both correct and consistent.

• Measurements are correct but inconsistent.

What should you do if your scale gives low accuracy and low precision results?

• Adjust the scale to add a constant value.

• Use it only for rough estimates.

• Continue using it as it is.

• Check the scale or technique for errors.
