Fill in the Blank

The SI unit for temperature is ___

Multiple Choice

If a thermometer consistently gives the same incorrect temperature reading, what does this indicate about its accuracy and precision?

• High accuracy, high precision

• Low accuracy, high precision

• High accuracy, low precision

Multiple Choice

In the dartboard analogy, what does it mean if all darts land close together but far from the bullseye?

• High accuracy, high precision

• Low accuracy, high precision

• High accuracy, low precision

• Low accuracy, low precision

Multiple Choice

Which of the following best describes the difference between accuracy and precision as illustrated by the dartboards?

• Accuracy is how close darts are to each other, while precision is how close darts are to the bull’s-eye.

• Accuracy is how close darts are to the bull’s-eye, while precision is how close darts are to each other.

• Accuracy and precision both mean how close darts are to the bull’s-eye.

• Precision is not related to the position of the darts.

Multiple Choice
