      the range of the process and the diffusion of the process
      the mean of the process and the dispersion of the process
      the average of the process and the stability of the process
      the range of the process and the distribution of the process

2. The cusum chart is an interesting chart that is used for monitoring variables and measurement on a continuous scale. (Points : 1)       True
      False
