Consider an experiment in which three operators were asked to make two measurements on each of 10 parts. The results are shown below: Operator 2 Operator 3 O Measurements Mean Range C-1 C-2 XC Rc 31.99 32.23 32.11 0.24 30.15 30.15 30.15 0.0 0.32 0.24 Measurements Mean Range B-1 B-2 XB RB 32.55 32.07 32.31 0.48 30.63 30.39 30.51 0.24 29.83 29.67 29.75 0.16 29.51 29.83 29.67 29.83 29.35 29.59 0.48 29.27 29.51 29.39 30.07 29.67 29.87 0.4 29.83 29.27 29.55 30.87 30.87 30.87 0.0 30.31 30.31 30.31 29.03 28.71 28.87 0.32 28.23 28.47 28.35 0.24 30.07 29.91 29.99 0.16 29.67 29.83 29.75 0.16 28.95 28.79 28.87 0.16 28.55 28.23 28.39 0.32 29.83 29.59 29.71 0.24 29.59 29.51 29.55 0.08 XB = 30.034, RB = 0.264 Xc = 29.722, Rc = 0.216 0.56 0.0 Part Operator 1 Mean Range RA A-1 1 2 3 4 A-2 31.83 31.67 31.75 0.16 30.31 30.47 30.39 0.16 29.51 29.83 29.67 0.32 29.43 29.27 29.35 0.16 5 29.91 30.23 30.07 0.32 30.47 30.31 30.39 0.16 28.79 28.79 28.79 0.0 29.99 29.67 29.83 0.32 28.55 28.63 28.59 0.08 29.35 29.11 29.23 0.24 A = 29.806, RA = 0.192 6 7 8 9 10 Measurements A.
