Question 2
Consider the following statements regarding precision in measurements of a quantity:
1) Precision is the measure of the spread of the incident errors.
2) precision is independent of the realizable correctness of the measurement.
3) Precision is usually described in terms of number of digits used in the measurement by a digital instrument.
