10. Which statement is true?
A. Leading zeros that precede nonzero digits are significant.
B. Accuracy can be assessed by calculating the percent error.
C. Accuracy cannot be improved by making replicate measurements and taking the
average.
D. All of the above are true.
Answer: B
Rationale: Accuracy is assessed by calculating the percent error. Leading zeros are not
significant, and accuracy can be improved by averaging replicate measurements .
11. Which statement is true?
A. Standard deviation is one way to quantify accuracy.
B. Precision is the agreement between experimental data and the "true" value.
C. Accuracy is the agreement between replicate measurements.
D. All of the above are true.
Answer: E
Rationale: All of the above are false. Standard deviation quantifies precision, not
accuracy. Precision is the agreement between replicate measurements, and accuracy is
the agreement with the true value .
12. Standard deviation is one way to quantify:
A. Accuracy
B. Precision
C. Percent error
D. Systematic error
Answer: B
Rationale: Standard deviation is a measure of precision (the spread of replicate
measurements) .
13. Accuracy is the agreement between:
A. Replicate measurements
B. Experimental data and the "true" value
, 4|Page
C. Standard deviation and the mean
D. Two different instruments
Answer: B
Rationale: Accuracy refers to how close a measurement is to the true or accepted
value.
14. Five nursing students measure the height of a patient. Which student used the
least precise scale?
A. Student A (157.48 cm)
B. Student B (157 cm)
C. Student C (160 cm)

Answer: C
Rationale: Student C recorded 160 cm, which has the fewest decimal places and is the
least precise .
15. Using the fact that 1 inch = 2.54 cm, 2640 ft equals how many kilometers?
A. 0.805 km
B. 0.00559 km
C. 0.0671 km
D. None of the above
Answer: A
Rationale: 2640 ft × 12 in/ft × 2.54 cm/in × 1 m/100 cm × 1 km/1000 m = 0.805 km .
16. What is the correct expression for the relationship between meters and
centimeters?
A. 1 m = 10 cm
B. 1 m = 100 cm
C. 1 m = 1,000 cm
D. 1 cm = 10 m
Answer: B
Rationale: 1 meter equals 100 centimeters .
17. Which SI prefix represents one-billionth?
A. Nano
B. Micro
C. Milli
D. Pico
Answer: A
Rationale: Nano- represents 10⁻⁹.
