Types of errors Flashcards
1
Q
Measurement error
A
The difference between a measured value and the true value.
2
Q
Anomalies
A
These values are in a set of results which are judged not to be part of the variation caused by random uncertainty.
3
Q
Random error
A
Present when any measurement is made and cannot be corrected. The effect can be reduced by making more measurements and calculating a new mean.
4
Q
Systematic error
A
Causes the reading to differ from the true value, by the consistent amount each time. It can not be dealt with by single repeats.
5
Q
If systematic error is suspected…
A
the experiment should be repeated using a different method or different set of equipment.
6
Q
Zero error
A
An indication that a measuring system gives a false reading. This results in systematic uncertainty.
