(a) What is the relationship between the precision and the uncertainty of a measurement? (b) What is the relationship between the accuracy and the discrepancy of a measurement?
a) Precision is the measure of how close a set of measurements are to each other, while uncertainty is the degree of agreement between a measurement and the true value.
b) Accuracy is the degree of agreement between a measurement and the true value, while discrepancy is the measure of how close a set of measurements are to each other.
c) Precision and uncertainty are unrelated, and accuracy and discrepancy are measures of the same concept.
d) Precision and accuracy both measure the closeness of measurements, while uncertainty and discrepancy are measures of different concepts.
