what are the possible errors of measurement?
Three main types of errors in measurement:
- Gross errors – calculation and recording mistakes
- Measurement errors – variations of a measurement from the true value
- Blunders – final source of errors caused by faulty recordings, wrong values, scale misreadings or forgetting a digit
There are two main types of measurement errors:
- Systematic errors – measuring device faults, Zero Errors, positive or negative
- Random errors – sudden changes in experimental conditions, noise and fatigue, voltage fluctuations, positive or negative
There are four main types of systematic errors:
- Instrumental errors – wrong instrument constructions, friction or hysteresis
- Environmental errors – external conditions, humidity, electrostatic or magnet fields
- Observational errors – wrong observations or reading of the instruments such as in energy meter readings
- Theoretical errors – caused by simplification of the model system such as system
temperature changes
