2. Suppose the expected value for the length of a meter stick is exactly one meter. A lab group checked the length of their meter stick and made the following measurements:
0.995 m, 0.998 m, 1.001 m, 1.000 m, 0.999 m

Which answer choice BEST describes these measurements?
A. accurate and precise
B. inaccurate and precise
C. accurate and imprecise
D. inaccurate and imprecise

3. Which of the following sets of measurements is the MOST precise?
A. 1 m, 2 m, 3 m, 4 m
B. 2.9 m, 3.0 m, 3.1 m, 3.2 m
C. 10 m, 20 m, 30 m, 40 m
D. 100 m, 200 m, 300 m, 400 m

4. Suppose you have a set of measurements.
What additional information would you need to describe the accuracy of the measurements?
A. the precision of the measurements
B. a second set of identical measurements
C. the expected value for the measurements
D. a set of measurements made with a different instrument

5.Which of these BEST describes the meaning of the term accuracy?
A. how likely a measurement is to be correct
B. how close a measurement is to what is expected
C. how likely it is that you will have to do an experiment again
D. how close one measurement is to other measurements of the same thing

6. What do scientists generally do if they are NOT sure what the expected value of a measurement should be?
A. use their best estimate for the true value
B. stop the experiment and measure something else
C. take the expected value from a different experiment
D. decide not to measure the accuracy of the experiment
