Key Stage 3
Meaning
A random error is when the results in an experiment are affected by an uncontrolled control variable.
About Random Errors
- Random errors cannot be predicted.
- A random error is just as likely to increase a result as decrease a result. This means if a reading is taken repeatedly over several experiments then an average can be used to reduce the effect of the random error.
