An error in measurement caused by factors which vary from one measurement to another.
- ‘Unlike random errors, systematic errors can be consistently either positive or negative.’
- ‘To detect reductions of this magnitude, however, both moderate random errors and moderate biases must be avoided.’
- ‘This demonstrates that replacement of electrodes increased random errors in our measurements.’
- ‘Otherwise, the random error in the estimates could easily dominate the variation of the estimates and blur the true variation pattern.’
- ‘Blood pressure measurement is subject to systematic and random error.’
