Question

Using percent error, determine if the measurement is accurate, precise, both, or neither. Explain why.

A) Accurate
B) Precise
C) Both
D) Neither

Answer 1

Accuracy and precision are two important factors when determining the quality of measurements. A set of measurements can be accurate if it is close to the true value, but not precise if the measurements are spread out. On the other hand, a set of measurements can be precise if they are close together, but not accurate if they are far from the true value

Step-by-step explanation:

Accuracy and Precision

Accuracy and precision are two important factors when determining the quality of measurements. Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close multiple measurements are to each other. A set of measurements can be accurate if it is close to the true value, but not precise if the measurements are spread out. On the other hand, a set of measurements can be precise if they are close together, but not accurate if they are far from the true value.

In this case:

a. Set a is precise, but inaccurate, because the measurements are close to each other but not close to the true value.

b. Set c is both precise and accurate, because the measurements are close to each other and close to the true value.

c. Set d is neither precise nor accurate, because the measurements are not close to each other and not close to the true value.
