Accuracy and Precision At a particular​ moment, the U.S. National Debt Clock says that the federal debt was $11,942,497,366.50. What is a good description of this​ reading? A) Very​ precise, but not necessarily accurate. It is quite precise because it seems to show the exact​ amount, but is not necessarily accurate because of a large relative error. B) Both very
