Table 5.7 is a complete GR&R example of three operators and two trials，measuring parts with specifications ±0.500.長 is obtained from the average R of the three operators and is equal to 0.0383. Xdiff is obtained from the difference between the highest average operator and the lowest and is equal to 0.0600.
GR&R% from specifications. If the specifications are given as ±0.500, then GR&R% = 0.2351/0.500 = 47%.
GR&R% from part variation. Taking the range of part averages from the data：
