Other questions in this quiz
2. What is the Precision of a Sensor
- A reduction in the bias in the measurements, removed through recallibration
- An instruments freedom from random errors
- The closeness of the agreement between the result of a sensor and the true value being sensed
3. What happens when a large number of readings are taken of the same quantity by a high precision device
- Very Small Spread of Readings
- Bias in measurand is increased
- Very Large Spread of Readings
- Bias in measurement is reduced
4. What is the accuracy of a measurement
- The closeness of the agreement between the result of a measurement and a true value of the measurand
- the freedom of a measurement from random errors
5. Causes of Low accuracy measurements from a high-precision instrument
- Bias in the measurand (can be removed through re-callibration)
- Bias in the measurements (can be removed through re-callibration)
- Number of Measurements is too high
- Number of Measurements is too low
