Question: In the context of problem, the density of a single pellet was repeatedly measured five times using a single device. How many measurands (xs), ys, s, and δs are there in this setting?
Problem: Pellet Densification. Crocfer, Downey, Rixner, and Thomas studied the densification of Nd2O3. Pellets of this material were fired at 1,400 ?C for various lengths of time and the resulting densities measured (in g/cc). In this context, what are the measurand (x), y, , and δ?
