AQA Science: Glossary - Anomalies

These are values in a set of results which are judged not to be part of the variation caused by random uncertainty.

e.g. Aaron records the current in a resistor for a certain voltage and takes repeat readings, some of which are shown below:

Resistance (Ω) current (A)

1 2 3 4 mean

20 0.25 0.28 0.47 0.26

30 0.16 0.17 0.15 0.16
