Quiz

1.3.1 Errors and Uncertainties – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
Which error is reduced by taking the mean of many readings?
zero error
calibration error
random error
systematic error
2.
A graph of y against x should pass through the origin but has a positive intercept, with the correct gradient. The likely cause is
a zero error
a random error
poor precision
a rounding error
3.
Readings are tightly grouped but all well above the accepted value. They are
neither accurate nor precise
accurate but not precise
both accurate and precise
precise but not accurate
4.
Which action best reduces the percentage uncertainty in a period measurement?
using a stopwatch with more digits
timing many oscillations
timing from a different starting position
using a heavier bob
5.
The resolution of a digital balance that shows 0.01 g is
0.01 g
0.001 g
0.1 g
1 g
6.
A systematic error is best found by
repeating readings
plotting more points
averaging the results
calibrating against a known standard
