1.
A result is precise but not accurate. This most likely indicates:
a systematic error
large random errors
too many repeats
no uncertainty
2.
Measured g = 9.7 ± 0.2 m s−2. The accepted value 9.81 is:
outside it
within the uncertainty range
impossible
the same as the mean
3.
The percentage difference between 52 and an accepted 50 is:
2%
0.4%
4%
40%
4.
Large error bars mean:
the data are very precise
the model is correct
there are no systematic errors
the data may fit several different models
5.
A graph that should pass through the origin has a clearly non-zero intercept. The best explanation is:
a systematic offset
random scatter
a perfect result
too many data points
6.
Which comment is best?
The graph was good
The gradient was 4.1 ± 0.2 s2 m−1, consistent with the predicted 4.0
There was human error
The results were fine
