The accepted value for the boiling point of water is 100˚C. During an experiment, students recorded the temperature observations listed below. Which one is the most accurate temperature for the boiling point of water?
A.) 103°
B.) 102°
C.) 95°
D.) 97°

Two students need to determine the density of iron for part of an experiment. Using the information in the table below, calculate the average of each student's trials. Which student has the most precise set of measurements? Which student's average is the most accurate?

A.) Felipe's measurements are more precise and his average is more accurate.
B.) Sarah's measurements are more precise and her average is more accurate.
C.) Sarah's measurements are more precise but Felipe's average is more accurate.
D.) Felipe's measurements are more precise but Sarah's average is more accurate.

Suppose you work at a theme park. Your supervisor wants you to make a sign displaying the maximum weight that a roller coaster train can carry. Your supervisor knows that the maximum weight is 1686.5 kg. However, he wants the sign to be quickly understood and tells you to make a sign that says: Maximum Weight 1700 kg. How could the lack of precision in this example cause problems?

The most accurate value for the boiling point of water is about 102°.

What is accuracy?

The term accuracy refers to the fact that the value is close to the accepted or the true value. The term precision refers to how closely bound together the values in a replicate measurement are.

Having said that, we can see that the most accurate value for the boiling point of water is about 102°. In the case of second question, the table is not shown hence the question can not be answered.

For the third question, we know that the value of the load that the roller coaster can carry is 1686.5 kg, when the sign says that the roller coaster can carry as much as 1700 kg, the roller coaster could become overloaded and become harder to move.
