thrown (yellow dots). The bottom image shows a nor-
mal distribution where the horizontal axis represents
the measurement value on the dartboard and the ver-
tical axis represents how common those values are.
The vertical line labeled "Reference Value" is directly
beneath the bullseye. This is our TRUE value that we
are trying to accurately and precisely measure. The
horizontal line A is the difference between the TRUE
value and the MEASURED value and line B represents
how spread out the darts are. In this diagram, lines A
and B represent what? [4]
A. A = Accuracy, B = Precision
B. A = Precision, B = Accuracy
6. Based on the above, which diagram represents a more A. A
precise measurement set? [4]
A. A
B. B
7. There are many ways to reduce inter-observer and B. It reduces in-
intra-observer error. One way is to have the same tra-observer error.
observer take measurements at the same time of day
with the same calipers. What does this accomplish?
A. It reduces inter-observer error
B. It reduces intra-observer error.
8. What if two different observers used the exact same A. It reduces in-
measuring equipment to measure different speci- ter-observer error
mens. This would have what effect?
