1. What does High Precision imply about measurement accuracy

  • Low accuracy is inversely proportional to high precision
  • Nothing is implied
  • High precision leads to high accuracy
  • precision can be represented linearly with accuracy

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
