Final answer:
Measurements can be precise but inaccurate, precise and accurate, or neither precise nor accurate.
Step-by-step explanation:
a. Set a is precise, but inaccurate. This means that the measurements in set a may have a small range of values, indicating precision, but they are not close to the true value, resulting in inaccuracy. For example, if a student measures the length of a pencil 10 times and consistently gets a value of 15 cm, while the actual length is 17 cm, the measurements are precise (consistent) but inaccurate (not close to the actual value).
b. Set c is both precise and accurate. This means that the measurements in set c have a small range of values and are close to the true value. For example, if a student measures the length of a desk 10 times and consistently gets a value of 100 cm, while the actual length is 99 cm, the measurements are both precise and accurate.
c. Set d is neither precise nor accurate. This means that the measurements in set d have a large range of values and are not close to the true value. For example, if a student measures the length of a bookshelf 10 times and gets values ranging from 90 cm to 150 cm, while the actual length is 120 cm, the measurements are neither precise nor accurate.
