Other questions in this quiz
2. Causes of Low accuracy measurements from a high-precision instrument
- Bias in the measurand (can be removed through re-callibration)
- Number of Measurements is too low
- Bias in the measurements (can be removed through re-callibration)
- Number of Measurements is too high
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
- Very Large Spread of Readings
- Bias in measurement is reduced
- Bias in measurand is increased
4. What does High Precision imply about measurement accuracy
- Nothing is implied
- precision can be represented linearly with accuracy
- High precision leads to high accuracy
- Low accuracy is inversely proportional to high precision
5. What is the Precision of a Sensor
- An instruments freedom from random errors
- The closeness of the agreement between the result of a sensor and the true value being sensed
- A reduction in the bias in the measurements, removed through recallibration
