Answer:
a. Student A has results that are neither precise nor accurate.
b. Student B has results that are both precise and accurate.
c. Student C has results that are precise but not accurate.
Explanation:
First, let's remember the concepts of accuracy and precision:
Accuracy is a measure of how close a measurement is to the correct or accepted value of the quantity being measured.
Precision is a measure of how close a series of measurements are to one another.
You can see this better in the following picture:
Based on this logic, you can note that:
- The results of Student A are not accurate and are not precise.
- The results of Student B are very close to each other which is precise and in turn, they are close to the real value which is very accurate.
- The results of Student C are very close to each other which is precise but it isn't close to the real value, so it isn't accurate.
The answers would be:
a. Student A has results that are neither precise nor accurate.
b. Student B has results that are both precise and accurate.
c. Student C has results that are precise but not accurate.
