Chapter 1: Problem 7

The measurements of length taken by a student are \(15.5 \mathrm{~cm}\) and \(15.6 \mathrm{~cm}\) whereas the true value is \(16 \mathrm{~cm}\). The measurement taken by the student are (a) precise (b) accurate (c) not precise (d) neither precise not accurate

Short Answer

Expert verified
The measurements taken by the student are precise but not accurate, so the correct answer is (c) not accurate.

Step by step solution

01

Determine Precision

Compare the student's measurements to each other. They are 15.5 cm and 15.6 cm, so they are very close to each other. This indicates that these measurements are precise.
02

Determine Accuracy

Now, we compare the student's measurements to the true value. The true value is 16 cm, but the student's measurements are 15.5 cm and 15.6 cm. They are quite close to the true value but not exactly the same. Thus, these measurements are not completely accurate.
